So is always good to invest in once self, than working under someone, which you won't have time for yourself,
Investing in oneself is always a choice of most people but some factors always hinder most people to do this. These factors include:
1. Starting Capital
2. Government policies (especially in some developing countries)
3. Which business to invest in
Lastly, education is always helpful in anything you are doing in life. An educated businessman will make it smoothly than an illiterate. Education is surely the best legacy.
I believe one should learn some skill rather than running after the school degree
They would learn the practial from the real world after having a degree.
