Passive income is a great tool for building retirement income faster, paying off debts, and, ultimately, retiring early and comfortably. If you have passive income during your retirement years, you potentially could live as well as you did during your peak earning years. Passive income is money you earn without doing actual labor. Often times, it comes from investments, such as in rental properties, stocks, bonds, annuities, and other investments.
Peer-to-Peer Lending: Earn up to 10% in returns by lending individuals, organizations and small companies who don't qualify for traditional financing through peer-to-peer lending platforms like Lending Club. You can lend $100, $1,000, or more to borrowers who meet lending platform financial standards. Like a bank, you'll earn interest on the loan - often at higher returns than banks usually get.
So many readers have asked me “How do you invest your money?”.  And so I’ve shared my thoughts on building a smartly diversified portfolio for long term returns.  Of course, this is great when you have a large capital base and 30-40 year time horizon.  For example if you are compounding at just 5-10% but doing it over 40 years and from a large starting base, plus you are topping it up monthly with new funds, you can enjoy ridiculous returns.
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.
