Sell photos. If you have a decent camera and a good sense of light, color, and composition, you can take and sell stock photos – i.e. nondescript images that lend themselves to many applications and are commonly used to illustrate online articles or products – with minimal effort. Stock photos of locations (a fire hydrant, a bare wall near an interesting tree, or anything you might find as a default background image on your computer) are easier to take, but stock photos of people (i.e. people arguing, people kissing, people laughing) usually sell for more, as they have more uses and require the written legal consent of your subjects. Hunt for a reputable stock photo dealer or database that will pay you fairly before signing on with anyone.
Companies like Uber and Lyft offer a great opportunity to make some quick cash. You'll need a clean driving record, a fairly new car and the authorization to work wherever it is that you live. If you have all of those things, you can work when it's feasible for you, whether that's in the middle of the day during rush hour, or in the wee hours of the night on a weekend. The choice is yours.
Start a small business. Being passionate usually translates to a superior product and better service, which is especially sought after in the age of the anonymous, 1-minute online review. Worried that there isn’t a market for your interests? The fact is that though you may not personally know many people who want what you have to offer, thanks to the internet, there’s a huge market for niche-products (pigeon diapers, chainmail wedding dresses, you name it)… and you might just end up being a trend-setter. To create an online store, you can either make your own website or, if don’t want to self-host, you can sell on eBay or a similar site.
I recently stumbled on the Trim app and I have to say, this one is a game changer. It’s a simple app that acts as your own personal financial manager. Once you link your bank to the app, Trim analyzes your spending, finds subscriptions you need to cancel, negotiates your Comcast bill, finds you better car insurance, and more. And of course, the app is free! My bet is that it will only take a few days for Trim to put an extra $100 in your pocket. So easy!
