There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.

Fear comes from uncertainty; we can eliminate the fear within us when we know ourselves better. As the great Sun Tzu said: “When you know yourself and your opponent, you will win every time. When you know yourself but not your opponent, you will win one and lose one. However, when you do not know yourself or your opponent, you will be imperiled every time.

Concentration is the root of all the higher abilities in man.

What you habitually think largely determines what you will ultimately become.

He who wants to succeed should learn how to fight, to strive and to suffer. You can acquire a lot in life, if you are prepared to give up a lot to get it.
