Odd jobs are easy to find.. buy and resell things from yardsales, ebay, etc. Wash cars. Mow lawns. Shovel snow from driveways in the winter. Collect and sell scrap metal, if you can cut down trees offer to chop wood for people, sell old video games or furniture and whatnot on ebay or craigslist, lots of way..

Depends on your age but I'm going with basic teen and under stuff you can sell old clothes to stores that buys them you could sell candy or holiday sweets you could baby sit your parents friends kids the options are endless
