Ability, experience and books have solution for all the problems.

We are limited by knowledge, not by courage.

I can lend you my money not my books.

If you don't find a good teacher, find a good book.

Your abilities are not enough to fulfill your wishes, so work considering your wishes and not your abilities.

People enjoy convincing others, if others are wrong they convince them towards right, if others are already right they still want to convince them towards wrong.
