School is the beginning of education, and people think that its goal is only to give you knowledge.
But the goal of the school should be to become useless.
School meets its goal when you have a burning desire to educate yourself, and when you try to hack things you just learnt.
Once it happens, you don't need a school anymore, you need a community to learn from other and share for other.
The best sign of success for a school is when you finally drop out because you learn faster than they can teach. The next step is finding your community.
