Digital Rebel

What are some good subjects to photograph? I recently bought a Canon Digital Rebel but I’m out of ideas. Help!?
Awhile ago I got into photography. Got myself a Sony Cybershot, took quite a few shots and now I’ve upgraded to a Canon Digital Rebel and all of a sudden, I ran out of photo ideas. Help please? It’s really important because I don’t want to have spent those money on nothing.
Oh kids today! Back in my day we had to walk 3 miles through the suburbs to buy CDs and 3 miles back. Oh they had public restrooms then…
Anyway
Go to the library and look for photography books (or the internet). Find something that you like and try to do it yourself. Shoot, screw it up, and shoot some more keeping in mind what you learned by screwing up the first batch. Wander your town and see what catches your eye. Youtube a new technique, such as long exposure or zoom blur. And if all else fails sit on it for a while and recharge your creative batteries.
