I wouldn't think of a high yield savings account as a source of passive income but your savings should be getting something (less like Seinfeld syndication residuals and more like a commercial jingle residuals!). It won't make you rich but it's nice if your baseline, risk-free rate of return on cash is 1% or more. The best high yield savings accounts (or money market accounts) offer higher interest rate and there is absolutely no risk. CIT Bank currently leads the pack with the highest interest rate.
You can try and start another travel blog, but every twenty-something who’s visited South East Asia has one; the market is so saturated that it will be very difficult for you to stand out and start making money. Instead, if you find something you’re interested in that is underserved, you’re far more likely to be able to carve out a space. You’ve a far greater chance of making money with a blog for vintage BMW owners than another generic Thailand travel guide.
Airbnb is a concept that has only been around for a few years, but it has exploded around the globe. Airbnb allows people to travel all around the world and to stay in accommodations that are a lot less expensive than traditional hotels. They do this by staying with participating Airbnb members who rent out part of their homes to travelers. By participating in Airbnb, you can use your residence to accommodate guests and earn extra money just for renting out space in your home.
Creating passive income is the key to retiring, especially retiring early. If you want to retire early with the stock market you will have to save a huge amount of money, because that money has to last so long and retirement calculators depend on you using your investment to fund your life. With passive income you will have income coming in as long as you own the investment, without every eating away at the principle invested. Creating passive income may take more work than investing in the stock market, but I think it is well worth the extra effort!
