Are each of us limited of how much we can learn?

It might simply be a matter of being too young to have had time to learn it all yet, or not having access to those who can instruct you.

Recent studies indicate that "stupid" people don't know they are stupid, they actually think they are smart. So the fact that you're asking this question means that you are probably a smart person who simply isn't applying him/her self well.

The younger u r the easier u learn.

There r tons of resource on the web. I think self-study is the most difficult way to study, I learn more from instructors.

i think everybody can learn something new. maybe at a lot slower pace then others but as long as you have an open mind. so long as you have a willingness to learn you can.
