Do you want to change the world? (Or rather, do you want to change the whole world but you’d settle for just changing part of it?) Then you need to read Guy Kawasaki’s latest book, Enchantment: The Art of Changing Hearts, Minds and Actions. In it, he explains how to influence what people will do while maintaining the highest standards of ethics.

In between his busy schedule at SXSW this year, Guy will be jumping on the Loopt Rewards Wagon, giving away signed copies of his latest book! Here’s how to take advantage of the Loopt Rewards Wagon at SXSW:

1. Download Loopt for your iPhone or Android device
2. Check in anywhere in Austin during SXSW, so we know you’re there.
3. Keep Reward Alerts “on” (you can adjust this in Loopt Settings > Notifications).
4. When you get a Reward Alert, launch Loopt to find the prize.
