betterphoto.com (some amazing photographers teach here whose attitudes are not at all condescending towards beginners or students of any abilities)

Learn the rules, study the rules, live the rules, then break them.
And look at photos you like, detach yourself from the happy photo brain, and study the composition of the photos, what did they do that you like, and look for that in the world around you.
For me it was slowing down and mentally going though the composition checklist. Looking though the viewfinder as if I was looking at a photo, and not worrying about the other stuff. I have also printed some of my photos on plain paper and drawn lines on them, and studied to see what happened.
