08065412441 is correct.

First clue is 080.

Second clue based on the condition of not being an odd number and greater than 5 is 6. 6 is an even number > 5.

You're right..I misread the second condition as "must be an odd number". Didn't see the "not" at first.
Re: Brain Teaser: What's The Professor's Phone Number by PriceActionZ: 6:45am On Apr 13, 2025
Ai don make us lazy.

Alright, let's tackle this phone number puzzle step by step. We have the disordered digits: 6, 4, 0, 0, 1, 1, 2, 8, 4, 5, 4. Our goal is to arrange these digits into an 11-digit phone number based on the ........... All shortened to avoid taking spaces.

This seems to satisfy all clues. Let's verify all clues:

1. "0 8 0" is present at start: 0 8 0 ...
2. First digit after "0 8 0" is 6 (even >5): yes.
3. Seventh digit is 1: position 7 is 1: yes.
4. Fifth and sixth digits: 5 and 4 (5-4=1, 5>4): yes.
5. Fifth and sixth >2: 5,4 both >2: yes.
6. Ninth and tenth same: positions 9,10 are 4,4: yes.
7. Eighth > last: position 8 is 2, last is 1: 2>1: yes.
8. 11 digits: yes.

### Checking for Other Possible Arrangements

Is there another possible position for "0 8 0"?

Let's try starting "0 8 0" at position 2:
- Sequence: _ 0 8 0 6 _ _ _ _ _ _ _
- positions 5,6: 5,4
- position 7: 1
- So: _ 0 8 0 6 5 4 1 _ _ _
- remaining digits: from original, used: 0,8,0,6,5,4,1; left: 4,1,2,4
- need to assign to positions 1,8,9,10,11
- but we have only positions 8,9,10,11 left (since position 1 is before position 2's 0)
- assign to 8,9,10,11 from 4,1,2,4
- digit9=digit10: so 4,4
- then 8,11: 2,1 (digit8>digit11: 2>1)
- position 1: no digit left, but we have two 1s used (one in position 7, one in position 11), but original has two 1s, so position 1 must be empty, which is not possible. Hence, this arrangement doesn't work.

Similarly, starting "0 8 0" at position 3:
- Sequence: _ _ 0 8 0 6 _ _ _ _ _ _
- positions 5,6: but position 5 is 0, which contradicts clue 5 (fifth digit >2). So invalid.

Starting "0 8 0" at position 4:
- Sequence: _ _ _ 0 8 0 6 _ _ _ _ _
- positions 5,6: 8,0, but position 5 must be 5 (from earlier), so conflict. Invalid.

Similarly, starting "0 8 0" at higher positions will conflict with positions 5,6 or 7. So the only valid arrangement is starting "0 8 0" at position 1.

### Final Verification

Let's write out the final sequence based on the first arrangement:

Positions:
1: 0
2: 8
3: 0
4: 6
5: 5
6: 4
7: 1
8: 2
9: 4
10: 4
11: 1

Phone number: 0 8 0 6 5 4 1 2 4 4 1

Check digits used:
Original digits: 6,4,0,0,1,1,2,8,4,5,4
Used digits: 0,8,0,6,5,4,1,2,4,4,1
Counts match.

All clues are satisfied.

### Conclusion

After carefully arranging the digits based on all the given clues and verifying each step, the professor's real phone number is:

**08065412441**

I Had Direct Contact with the President… Until I Asked for N100,000.

He always picked my calls. Always responded.

Then one day, I had an emergency. An urgent need.
I called him and said, “Sir, please I need N100,000.”
He said, “Okay.”
He told someone to send it to me.

Then he blocked me.

Now, that’s not a true story, but it perfectly explains how people lose life-changing relationships.

At this point, you should stop reading if you don’t want the truth that hurts.

The potential investor is not the same man you ask for urgent 2k.
The one meant to teach you how to build your own farm is not the one you call to “buy you breakfast”

If you confuse the roles,
You lose both the man and the opportunity.

Some people are doors.
Some are ladders.
Some are mentors.
Some are investors.
And some are not meant to fix your hunger.

Rich and powerful people don’t keep needy friends.
They keep useful ones.
If they sense you are drowning in basic survival, they will toss a life jacket and sail off without you.

Why?

Because in their mind, “you don’t belong here yet.”
They will place you back where the crowd is.
No beef. Just instincts. Standard.

An eagle doesn’t keep friendships with a fowl.
Not because the fowl is bad but because they fly at different altitudes.

If you want to keep high-value people, stop trying to use them for survival. Survive secretly and build with them openly. They are not there to help you survive, and out there, no one gives a flying f**k how you feel.

That’s how to maintain access.

You must not become an unnecessary burden if you want to keep the relationship.

This truths hurt, it sounds harsh and wicked, but this post is not about what’s morally right or wrong. I’m simply sharing a CODE.

Do You Know…..

If you have internet access, food in your kitchen, a roof over your head, and a bed to sleep on, you are already richer than over 65% of the world.

Yes, you may not drive a Benz.
You may still be figuring out your life.
You may not even have ₦5,000 in your account right now.

But you are not poor.
You are just in process.

There are people praying to have the life you are complaining about.
Never let comparison blind you to the quiet blessings you already have.

Gratitude is wealth. Perspective is power. And patience will build you a fortress of fortune.

1) When someone lends you money, return it even before they ask for it. If you're unable to repay, keep them updated regularly. Don't just go silent on the person.

2) When you visit someone's house, don't go through their fridge. Stop asking if you can take this or that. Stay in one place and respect their space.

3) Don't ask people unnecessary questions. Apply emotional intelligence when inquiring about something. If someone had a miscĂĄrriage, avoid asking about their pregnancy. If someone dropped out of school, don't bring it up. Such questions can rĂşin their mood. If they don't mention it, it's best to pretend you don't know.

4) When someone is having a discussion with you, put your phone away. It shows you're concerned and paying attention. Being distracted by your phone can give the impression you don't care, and it's disrespectful.

5) Don't visit people unexpectedly. Let people know you're coming ahead of time. It shows respect for their schedule and space.

6) When you enter a room and meet people, greet everyone, not just the person you know. It shows respect and kindness to everyone present.

7) Try not to spitt in front of people. It's really disgĂťsting. And if you want to sneeze, use a tissue or handkerchief to cover your mouth.

cool When you take your children to someone's house or an event, keep them under control. Ask them to stay one place and avoid running around. This helps avoid inconveniencing your host and others. They might not feel comfortable telling you. Some might wĂĄrn you.

9) When you're with your partner in public, avoid yelling at your partner using abĂťsive words. It creates an impression that you're abĂťsive at home.

10) When you visit someone's house, know when to leave. Don't overstay your welcome. No matter how sweet the conversation is, know when it's time to leave.

11) Don't comment on someone's appearance negatively. You don't know what's going on in their lives.

12) When talking with someone in a public space, be mindful of your tone of voice. Stop shouting.

13) When you see someone in public or at an event, don't over stare. It could make the person feel uncomfortable.

14) Don't focus too much on your phone when you're in public. It can make you shy.

15) If you're someone who cĂşts people off immediately when they offend you, it may affect your social life. Unless the person poses a thrĂŠĂĄt to your life or mental health, try to be more understanding and forgiving. Condone people. Everyone has their own weaknesses, even you.

16) Don't be fond of disclosing people's secrets without their consent.

17) Learn to appreciate people when they do something for you, even if you're paying them. It motivates them to do more and deliver better results.

18) When you're having a discussion with someone, listen to understand, not just to respond. And don't dominate the conversation.

19) Don't brag about your achievements around friends who haven't reached the same level. It can cause jeĂĄIousy and eĂąvy. Even if they smile and pretend to be happy, a part of them feels like you're overtaking. It's natural and human nature.

20) The fact that someone is friendly with you doesn't mean they want to be friends with you. Understand boundaries. Stop trying to turn all casual friendships into a romantic affair. You could end up losing both.

Let’s be honest.

You’re tired.
You borrow to eat.
Borrow to pay rent.
Borrow to look responsible.
But deep down, it’s not working.

You're not wicked…
You're not lazy…
You're just overwhelmed.

📌But you can break free. You MUST

Real Steps to Stop the Borrowing Trap and Reclaim Your Life

1. Stop Borrowing to Impress.
Don’t buy clothes or gadgets to prove you’re okay. You’re allowed to look broke while fixing your life. Real people will understand.

Even the rich somtimes deliberately look broke.

2. Make a List of What You Owe.
Write it down. Don’t fear the figures. Facing your debt is the first step to freedom. Ignoring it will only multiply the shame and anxiety.

3. Call the People You Owe.
Yes, it’s hard. But call them. Apologise. Be sincere. Tell them your plan to repay gradually. Most people respect honesty more than silence. Don't owe people and be bullying them on top.

4. Cut Down to the Bone.
If it’s not a NEED, pause it. Cancel all subscriptions. Stop eating out. Your survival is more important than soft life right now.

5. Start Earning Something Daily.
Don’t wait for big jobs. Sell data. Resell perfumes. Offer cleaning. Teach online. Babysit. Small daily income keeps you away from daily debt.

6. Learn Financial Literacy.
Many of us were not taught how to manage money. Follow pages that teach budgeting, saving, and growing income. Attend free money classes online.

Certainly! Here's a heartfelt and respectful ode to a former high school principal known for being a disciplinarian, blending admiration with the lasting impact of their leadership:


---

🖋️ Ode to the Disciplinarian Principal

O captain of the corridors, stern yet wise,
With iron glance beneath those seasoned eyes.
You walked the halls with quiet, thunderous grace,
A ruler not of fear, but of a higher place.

The bell would ring, and silence swiftly fell,
Your presence spoke what no loud voice could tell.
A sentinel of learning, order’s flame,
In every echoed footstep, bore your name.

You carved from chaos rules both firm and just,
Taught us that boundaries are built on trust.
Your discipline—no lash, no shameful scorn,
But steady hands by which young minds were born.

We feared, it's true—but more, we knew your care,
Your sharp rebuke was love clothed in despair.
For every late slip, every tardy call,
You raised us upright so we would not fall.

Now time has dimmed the paint upon the wall,
But echoes of your footsteps grace the hall.
The rebel’s fire, the scholar’s trembling pen—
All tempered by your will, and forged again.

You’ve passed the torch, but still we feel your spark,
A guiding flame through every shadowed dark.
Oh Principal, both hammer and the scroll,
You shaped the clay and helped us find our soul.
