You are never too old to become younger!

A man can't soar too high, when he flies with his own wings.

You must find the place inside yourself where nothing is impossible.

The secret of health for both mind and body is not to mourn for the past, nor to worry about the future, but to live the present moment wisely and earnestly.

Everything you can imagine is real.

If you are humble nothing will touch you, neither praise nor disgrace, because you know what you are.

If you get up in the morning and think the future is going to be better, it is a bright day. Otherwise, it's not.

March on. Do not tarry. To go forward is to move toward perfection. March on, and fear not the thorns, or the sharp stones on life's path.

You can chain me, you can torture me, you can even destroy this body, but you will never imprison my mind.

I'm not telling you it's going to be easy - I'm telling you it's going to be worth it.

People throw stones at you and you convert them into milestones.

Always do what you are afraid to do.

If you spend too much time thinking about a thing, you'll never get it done.
