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.

What I did: I first identified my favorite places in the world to live: San Francisco, Honolulu, Paris, Amsterdam, New York City, and Lake Tahoe. I then looked up the median rent and housing prices for each city. Then I factored in private education costs for two kids to be conservative given I may not have two kids and public schools are often good enough. After calculating all vital costs, I then did a self-assessment of how happy I was making $50,000, $100,000, $150,000, $200,000, $250,000, $350,000, $500,000, and $750,000. I decided working 20 hours a week making $200,000 a year is the best income balance for maximum happiness.

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.
