Words to live by

Thoughts I steal often.

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. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it.

Steve Jobs

A computer once beat me at chess, but it was no match for me at kick boxing.

It’s hardware that makes a machine fast. It’s software that makes a fast machine slow.
