A lot of great thinkers- like Einstein and Newton- come up with their best ideas when they're young because they don't yet think in the way that the establishment teaches them. Sometimes your lack of knowledge frees your mind to be creative and think in a different way. But you still have to be logical and figure out a practical way to get things done, even though you're looking at things differently.
As the best wine doth make the sharpest vinegar, so the deepest love turns to the deadliest hate.
