No man will make a great leader who wants to do it all himself or get all the credit for doing it.

Do your duty and a little more and the future will take care of itself.

You can't build a reputation on what you are going to do.

I don't think anything is unrealistic if you believe you can do it.

May we never let the things we can’t have, or don’t have, or shouldn’t have, spoil our enjoyment of the things we do have and can have. As we value our happiness, let us not forget it, for one of the greatest lessons in life is learning to be happy without the things we cannot or should not have.

Don't let life discourage you; everyone who got where he is had to begin where he was.

Practice hope. As hopefulness becomes a habit, you can achieve a permanently happy spirit.

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

Imagination is everything. It is the preview of life's coming attractions.

Believe nothing, No matter where you read it, or who said it even if I have said it, unless it agrees with your own reason and your own common sense.

"By recording your dreams and goals on paper, you set in motion the process of becoming the person you most want to be."

"Have courage for the great sorrows of life and patience for the small ones; and when you have laboriously accomplished your daily task, go to sleep in peace."

Say "Yes" to the seedlings and a giant forest cleaves the sky. Say "Yes" to the universe and the planets become your neighbors. Say "Yes" to dreams of love and freedom. It is the password to utopia.

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

"The only disability in life is a bad attitude."
