When every physical and mental resources is focused, one's power to solve a problem multiplies tremendously.

The mind quickly responds to teaching and discipline. You can make the mind give you back anything you want.

You must never conclude, even though everything goes wrong, that you cannot succeed. Even at the worst there is a way out, a hidden secret that can turn failure into success and despair into happiness. No situation is so dark that there is not a ray of light

Don't take tomorrow to bed with you.

You have a choice everyday... You can choose every morning whether you will be depressed and miserable, or whether you will be happy.

I've got great faith in the essential fairness and decency - you may say goodness - of the human being.

Stop resisting your problems so furiously in your mind. Stop struggling to solve them. If you do that, a great sense of peace followed by a great sense of power will come to you.
