A clever person solves a problem. A wise person avoids it.

Speak only if it improves upon the silence.

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

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

He who is not contented with what he has, would not be contented with what he would like to have.

You should be the change that you want to see in the world.

We are what we repeatedly do. Excellence, then, is a habit.

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

To believe in something, and not live it, is dishonest.

Change before you have to.

Find purpose, the means will follow.

Seven social sins: politics without principles, wealth without work, pleasure without conscience, knowledge without character, commerce without morality, science without humanity, and worship without sacrifice.

Whatever you do will be insignificant, but it is very important that you do it.

Truth alone will endure; all the rest will be swept away before the tide of time.

My life is my message.
