The greatest discovery of my generation is that a human being can alter his life by altering his attitudes.

Life must be lived as play.

Everything in life is luck.

Life is either a great adventure or nothing.

Change is the law of life. And those who look only to the past or present are certain to miss the future.

Life is like dancing. If we have a big floor, many people will dance. Some will get angry when the rhythm changes. But life is changing all the time.

Change your life today. Don't gamble on the future, act now, without delay.

If life were predictable it would cease to be life, and be without flavor.

It is one of the beautiful compensations in this life that no one can sincerely try to help another without helping himself.

We are here to add what we can to life, not to get what we can from life.
