Other people's views and troubles can be contagious. Don't sabotage yourself by unwittingly adopting negative, unproductive attitudes through your associations with others.

It is difficulties that show what men are. For the future, in case of any difficulty, remember that God, like a gymnastic trainer, has pitted you against a rough antagonist. For what end? That you may be an Olympic conqueror; and this cannot be without toil.

Man is troubled not by events, but by the meaning he gives them.

To know that you do not know and to be willing to admit that you do not know without sheepishly apologizing is real strength and sets the stage for learning and progress in any endeavor.

Don't demand or expect that events happen as you would wish them do. Accept events as they actually happen. That way, peace is possible.

We should do everything both cautiously and confidently at the same time.

If you would be good, first believe that you are bad.
