We've all heard that we have to learn from our mistakes, but I think it's more important to learn from successes. If you learn only from your mistakes, you are inclined to learn only errors.

Make a mental list of happy thoughts and pass them through your mind several times every day.

Keep thinking, keep interested, keep praying, keep dreaming. Be mentally sensitive at all times so that the magic word that motivates you may one day speak to your deep inner self.

The man who lives for himself is a failure; the man who lives for others has achieved true success.

Expecting the best means that you put your whole heart (i.e. the central essence of your personality) into what you want to accomplish. People are defeated in life not because of lack of ability, but for lack of wholeheartedness. They do not wholeheartedly expect to succeed. Their heart isn't in it, which is to say, they themselves are not fully given.

Change your thoughts and you change your world.

Nothing can stand in the way of the man who focuses his entire self on a problem.
