If you live in a cold area of the country and not everyone in your town owns a snowblower. Go out with a shovel and make some money. It is very easy to do, get out early, especially if you're off from school. Charge by the job, offer to do driveways, find potential clients by finding snow covered sideways. If you've never done this, you should try it. It is easy. I did it when I was a kid and ended up making more than a hundred dollars on multiple occasions. People are afraid of being trapped and they will pay you to dig them out.
