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.

Intelligence is the ability to adapt to change.

If you want to teach people a new way of thinking, don't bother trying to teach them. Instead, give them a tool, the use of which will lead to new ways of thinking.

Education is the most powerful weapon which you can use to change the world.

Those who cannot change their minds cannot change anything.

No matter what people tell you, words and ideas can change the world.
