Steve Jobs at the 2005 Stanford University Commencement address:
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.
I hadn't read this speech in a while, but I did so today. It's a great speech and every time I read it I find something I hadn't noticed before. To me, that's what makes something great, be it a film, a book, a photograph, or even a person. Anything that delivers an amazing first impression and then keeps on delivering more and more is something worthwhile.
This time, the above quote stood out given what I wrote a few days ago.
