However, like anything else truly worthwhile, apps require a significant investment of your time or money upfront. If you don't have the skills, then you have to hire someone who can assist you in creating a great app. But first you need to come up with an idea that will sell. Do the proper market research and analytics to come up with the right app.
If you have a propensity for writing and you can slay with your prose, consider writing an ebook. While the market has certainly become saturated as of late, books that help teach people about a technical topic still sell extremely well. This is a great source of passive income but does require a large amount of effort at the outset before any money is generated.
Before having my own website, I spent time reading websites, newsgroups, bulletin boards and forums about the game, and eventually started trading online. Back before search engines were any good most of my time was spent in particular Magic newsgroups, some that talked strategy, and some that were focused specifically on trading and/or buying and selling cards.
Hold a yard sale. If you have a yard or garage and plenty of items to sell, you can have a yard sale as early as tomorrow. By advertising your sale on local Facebook pages and Craigslist, you can also skip the paid newspaper ad and keep all of the profits for yourself. If you don’t have time to price everything, try asking patrons to “make an offer” or grouping similar items on tables with an advertised price (e.g. everything on this table is $5).
Private coaching, like consulting, is another situation where you trade time for dollars, but in terms of your hourly pay rate it is hard to find a higher paying “job”. Of course you don’t have to start off charging thousands of dollars. Depending on your expertise and what kind of outcome you help people achieve, will determine how much you can charge. Offering coaching for $100 per session is not out of reach for most people, and that’s not a bad starting rate if you are looking to build up your experience through helping others closely.
As the Internet continues to evolve, opportunities to earn supplementary and full-time online income will grow. The very definition of work in an information-based economy is evolving, with traditional full-time jobs disappearing in favor of different arrangements (e.g. self-employment, flexible schedules, changing skill sets, etc.). In this respect, giving it a try can open up new career and business options.
What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
