I'll share an exercise that been very good for me, and June 1 would be a great time to begin it. It's simply to simply take one finished picture a day and post it to a web site like Flickr, Photobucket, Smugmug, etc. By "finished," I mean photoshopped or otherwise edited -- a complete effort from start to finish. Don't worry about perfectionism -- just do the best you can each day, then move on.
It's good for your photography because it forces you to shoot in your own environment -- around the house, school, your job, etc. You quickly exhaust all the obvious subjects, and then you have to look and think. In doing that, you discover subjects you hadn't thought of before. Also if you especially like a subject -- or if you think you could do better -- you can go back and shoot it again the next day. It's a kind of visual diary -- try it, and see how long you can keep it up. It's not as easy as it sounds.
