There are two primary choices in life: to accept conditions as they exist, or accept the responsibility for changing them.

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

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

Appearances matter and remember to smile.

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.
