One should think about their skills, hobbies and basic daily habits as well. Do you like to cook? Be a personal cook or dinner parties. Baking? Make wedding cakes or cupcakes for weddings/special events. Do you enjoy cleaning? Trying going to banks/repo companies and ask if they are in need of a repo cleaner or market yourself as a all-around cleaner. Know how to mow a lawn? Get paid to do it in your neighborhood. Sell products from large companies – Jewelry in a candle, Sentsy, Health and home products – etc.
Good list. Some definitely good examples, if people really want to try. I think “interview other people and sell the interviews” will work the best. Or just build a website and post those interviews. I have managed a few websites where we interviewed people and those get a lot of visits from Google searches. For anyone out there willing to interview people I would recommend it, it will make you money.
