The Holstee Manifesto makes me smile every time I read it. Even if I'm in a meh mood, I find I can't get to the end of it without feeling at least a little pumped. Life is short. Live your dream and share your passion. Amen.
If you need a bit more Holstee Manifesto in your life, you can buy it as a poster or simply download for free as a background for your desktop/phone/tablet.
