School is just a place where you learn the basic of some subjects. What life teaches you, no school in this world can teach. If you are working sincerely and with full devotion, nothing can stop you from getting success.
Bill Gates of Microsoft is a good example. He left his school, only to pursue his passion that was computer programming. You will always win if whatever you do is with passion. It may be cooking, programming or driving.
Generally, people in this world can give suggestions to everyone, expect do their own work properly. I believe if you focus primarily on your own work, nothing can stop you for getting success in life.
