It is not fair to ask of others what you are not willing to do yourself.

Do the things that interest you and do them with all your heart. Don't be concerned about whether people are watching you or criticizing you. The chances are that they aren't paying attention to you.

...no matter how avid they themselves may be for praise and appreciation, people are often niggardly in giving it to others, however merited it is.

Beautiful young people are accidents of nature, but beautiful old people are works of art.

If everything was in your favor, if you did not have to surmount any great mountains, then you have nothing to be proud of. But if you feel that you have special difficulties, then you must indeed be proud of your achievement.

You must do the things you think you cannot do.

You get strength and courage, when you stop to look fear in the face.
