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.
Now, if you don’t know people who might want your coaching services, there are a number of online tools and communities that make it incredibly easy to find clients and teach, on just about any topic area you can think of. Community driven platforms like Savvy.is, Clarity.fm, and Coach.me provide you with a network of potential clients to interact with, as well an integrated payment solution.
If you design a wildly popular app (which is harder than it sounds), you might be pleasantly surprised with the income they generate. Offering one or more apps at the iTunes or Android app store gives your creations wide exposure to prospects. And income can be generated by charging for the app, displaying in-app ads, or charging for in-app features and upgrades.
What does that mean for you? It means Nielsen will pay you $50 a year to keep their app on your favorite internet browsing device. The app itself collects statistics on your internet usage anonymously, so you never have to worry about any data being linked to you. And the best part is, the app takes up barely any space and doesn’t slow down your phone or tablet at all!
