An excerpt from the commencement speech Steve Jobs gave at Stanford University:

“You’ve got to find what you love. . . .Your work is going to fill a large part of your 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.”  –Steve Jobs

(If you have never read or watched this speech, I highly recommend you google it and read/watch it. It is very inspiring!)
