I think Steve Jobs was a very brave man.He dropped out bravely and fed himself.The old saying that success, strength and luck are indispensable.So I think Steve Jobs's success was not just because of his wisdom, but also because of his luck.
And I don't think you should ever do something you regret. If you do, don't regret it. As long as you don't feel wrong at the moment, stick to it. I believe that one day you will feel your decision today.
