It is my firm belief that education teaches the intelligence right out of us.
Be careful what you learn. Be careful from whom and from where you learn.
Question everything. Everything.
Remember that a "well-educated" person is only as smart as the second-year grad student who wrote the book for the professor so they could maintain their tenure.
I'm not saying you shouldn't educate yourself. It helps to share knowledge. The problem is this: two-thirds of a human is water. Water has no capacity for intelligence. So it stands to reason that two-thirds of everything you learn from your fellow water-bag is unintelligent. It's bunk.
I'm drinking Smart Water right now. I'm not learning a damned thing. I'm not sure I trust another flesh-bag of water to tell me what I need to think.
It's the sorting out of bad v. good learning that makes you intelligent, not the learning itself. Only one-third of everything you learn is valuable, statistically speaking.
And remember Edison and Einstein both abandoned traditional education. Einstein preferred to study on his own, and Edison was kicked out entirely as being too dull to learn.
