Bullshit. If you have a job, you have marketable value. Maybe it’s low value, if you’re flipping burgers, but you can create value somehow. I don’t care if you have to start out by re-renting the parking spot in front of your apartment, you can find, create, or buy something valuable worth repeatedly selling or renting, or you’re not thinking hard enough. Here’s a free idea: A lot of people want to play with 3D printers. Get 5 of your friends together and buy one. Put up a website and a listing in the local paper. Charge $50/h for printing. Set up a system that verifies if payment has been submitted and then automatically prints out the files that have been emailed to you. Split the earnings with your friends. Boom. You have passive income.
Truebill is an app that helps you save money by identifying recurring subscriptions and other bills and helping you cut costs by negotiating better rates and fees.

I've got a $185,000 CD generating 3% interest coming due. Although the return is low, it's guaranteed. The CD gave me the confidence to invest more aggressively in risk over the years. My online interest income has come down since I aggressively deployed some capital at the beginning of the year and again during the February market correction. You'll see these figures in my quarterly investment-income update.

Create a website or blog. With the foundation of a good website, you can build traffic (a flow of visitors to your site) that you can then convert into revenue sources later on. First, you have to get the traffic, so start by writing about what you know on your website or blog. If it is interesting, informative, and well written, you may gain consistent traffic to your site over time.[6]
If you have specialized knowledge in a certain topic, you can put together an online course to teach others. For example, if you have experience in real estate investing, you can create an online course “Real Estate Investing 101”. The benefit of an online course is that once you create the course material, you can sell it to as many people as you want.
