I've been playing around with Adobe Photoshop for several years but I've made it a point to get good at it this summer. My ideas to improve are as follows:

• Tutorials (I try to do one everyday).
• Reverse-Design Websites (?)
• Compete in Design Contests - not necessarily to win. Just so you can apply concepts learned in tutorials.

Anything else you guys can think of? How did you get good at design?
