maybe make your bed, walk the dog if you have one, give the dog a bath, help clean up the house, or like i have to do sometimes is empty all f the trash cans out through out the house. little things like that can get you some money.
This time of year is a great one for earning money cleaning up lawns. Raking gravel out of the berm at the edge of the road, raking any leaves that fell after the lawn was raked last fall, etc. Good for you for being enterprising and not asking,"How can I get money without working for it?" like some do on here.
