majority have along the line discovered that despite all the rigorous times they passed through in school to became a successful person( secure a perfect job) after graduation, circumstances have disappointed them. but the big question is should they continue in search for job or quit and forge a way out by starting their own business? because majority are still under the spell of job searching that yields no positive result.

I am a victim. After spending many years in school studying electrical/electronics engineering coupled with internal and external strike, not forgetting another compulsory year for NYSC, I'm starting to think the way forward for now is to be my own BOSS. I gotta be straight with you... Nigeria is frustrating and tiring. Anyone who's got the opportunity to jet out this country shouldn't think twice.

Both.
You can start building your own business while searching for a job. Even after you get a job, another source of income is advised because you may be sacked anytime.

but if one started building his own bizness , I think there is no need search for job again. instead, he should just focus and pay attention to business on ground without an attention divide

"Mind Your Own Business". I will advised that one should start a business or rather be an entrepreneur.

With just a meagre amount you can start a recharge card business.
