The greatest glory in living lies not in never falling, but in rising every time we fall.

The secret of change is to focus all of your energy, not on fighting the old, but on building the new.

Be the change that you wish to see in the world.

Do not judge me by my successes, judge me by how many times I fell down and got back up again.

Lead from the back and let others believe they are in front.

You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.

I have never let my schooling interfere with my education.

Everyone thinks of changing the world, but no one thinks of changing himself.

Those who cannot change their minds cannot change anything.
