We are what we repeatedly do. Excellence, then, is not an act, but a habit.

Life is what happens when you're busy making other plans.
The only true wisdom is in knowing you know nothing.
The future belongs to those who believe in the beauty of their dreams.
In three words I can sum up everything I've learned about life: it goes on.
It does not matter how slowly you go as long as you do not stop.
Don't cry because it's over, smile because it happened.
The only way to do great work is to love what you do.
The best way to predict the future is to create it.
Happiness is not something ready made. It comes from your own actions.

You must be the change you wish to see in the world.
