I hate working hard

I want to create things, and I do. I can never get myself beyond the point of simple demos and experiments, because I severely dislike working.

I fail school classes, I disappoint people, most importantly myself and I fail to finish simple tasks, only because I do not work hard.

Where do I go with this? I want to create things, but lose my motivation when it becomes hard.

How are others dealing with these kind of problems? I'm sure I cannot be the only person with a paradoxical lazy-ambitious attitude here.
