>>The reason is that if you're truly good at something, if you have a real talent for it, then it's easy for you to do it well from the start, so you rarely judge it or realize how good you are.

I've often wondered about this (beyond basic abilities). I'm sure there are exceptional people for whom this is true but in my experience most people start out not being very good at what they later end up being really good at.

Would love to know if there's some sort of data / research on this.
