Lessons Life Has Taught You?

The more we grow, the more we learn. I guess life has taught us different lessons using different methods. I would just like us to share the lessons life has taught you.
For me, life has taught me alot of lessons but guess what is on my mind now is that life is not fair.I have some personal experiences. Life is not fair and that is why you need favour from God.If no be GOD. Never expect life to be fair on you and that is why you need God or how can you explain some things happening today.
The good people die,bad people live long.
Some people can't afford 3 square meals,
Some people have enough money for their 3 generations,
Some people are born into wealthly families,
Some people are poor into poor families.
So many examples like that.

So what lessons has life you has a person.

Life has taught me that You get whatever you earn.

What ever you expect from life. Life will give it to you.

Believe it and you will achieve it.
