Basically, people that tend to be more 'intelligent'/'successful' are better at learning. You optimize learning in a similar fashion to a start-up. By failing fast.
In general I think you tend to hear alot of silly thoughts from very 'intelligent'/'successful' people because they tend to speak their thought often and early (even if they do not have a grasp on it yet). Which leads to quick correction and refinement. Or in other words faster learning.
