The greatest sin is to think yourself weak

Courage is the thing. All goes if courage goes.

Do not count your chickens before they are hatched.

The great art of life is sensation, to feel that we exist, even in pain.

Give yourself something to work toward - constantly.

Motivation is what gets you started. Habit is what keeps you going.

If you fell down yesterday, stand up today.

No leader can be too far ahead of his followers.

The past cannot be changed. The future is yet in your power.

I hated every minute of training, but I said, 'Don't quit. Suffer now and live the rest of your life as a champion'.

If you enter this world knowing you are loved and you leave this world knowing the same, then everything that happens in between can be dealt with.

If we command our wealth, we shall be rich and free. If our wealth commands us, we are poor indeed.

No one is free who has not obtained the empire of himself. No man is free who cannot command himself.

This is one small step for a man, one giant leap for mankind.

To go too far is as bad as to fall short.

Out of intense complexities intense simplicities emerge.

The key to immortality is first living a life worth remembering.

A bird doesn't sing because it has an answer, it sings because it has a song.

Start by doing what is necessary, then what is possible, and suddenly you are doing the impossible.

My heroes are the ones who survived doing it wrong, who made mistakes, but recovered from them.

We travel. Some of us forever. To seek other states, other lives, other souls.
