Live as if you were to die tomorrow. Learn as if you were to live forever.

The world is a dangerous place to live, not because of the people who are evil, but because of the people who don't do anything about it.

Success is going from failure to failure without a loss of enthusiasm.

Science without religion is lame, religion without science is blind.

You have enemies? Good. That means you've stood up for something, sometime in your life.

Don't count the days, make the days count.

Change before you have to.

Find purpose, the means will follow.
