Some of the smartest people I know never even finished school. Getting good grades in school only means you're good at regurgitating information. I prefer to be a free thinker, come to my own conclusions. I did 4 years of university. It's largely a scam unless you're wanting to be a doctor or similar. The best way to learn is on the job, not from a text book. Unfortunately as a society we have been convinced otherwise to our own detriment.
