And while it will take time to build up a big-enough audience to attract advertisers and other ways to make extra income from your podcast, the opportunity is there. John Lee Dumas interviews entrepreneurs seven days a week for his podcast Entrepreneur on Fire and now makes more than $200,000 a month from it. In fact, John publishes all his income online and showed that he’s made almost $13 million since launching in 2012.

Holly told me she started writing content in 2011. At the time, she still worked a full-time job but created content online part-time to supplement her income. Over time, she was able to double and triple her rates until she could quit her full-time job to write. These days, she makes bank as a freelance writer and teaches others to do the same via her online course, Earn More Writing.

Know the difference between an asset and a liability. The dividing line is whether it puts money in your pocket, or takes it out.[4] As much as you love your home, for instance, it is a liability rather than an asset because you put more money into it than you get out of it (unless you're flipping it or renting it out). Whatever money you save, invest it in assets such as stocks, mutual funds, patents, copyrighted works--anything that generates interest or royalties. Eventually, you might get to the point where your assets are doing the work for you, and all you have to do is sit there and make money!

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!
