The only limit to our realization of tomorrow will be our doubts of today.

When you want to succeed as bad as you want to breathe, then you'll be successful.

"Un libro es una conversación íntima entre el autor y el lector a través del tiempo."

译文：想要打败它，一定要暂且帮助它。想要取得利益，必然要先给予一些利益。

True strength comes from vulnerability and the courage to be yourself.
