"You've got to find what you love. And that is as true for your work as it is for your lovers. Your work is going to fill a large part of you life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking until you find it. Don't settle."

Steve Jobs, Stanford Commencent Speech in 2005.
