1. Photography
Photography is a relaxing hobby that will most likely give you financial satisfaction. Whether you’re a beginner or not, create an account as a photographer of Fiverr.com, the online marketplace where people find freelance services such as photography.
You can also sell your best photos on stock websites like BigStock, Shutterstock, Dreamstime, or Stock. Another easy way to earn money from photography is freelancing for Airbnb. By simply taking photos of rentals, you can make a big chunk of money while traveling.
P.S.: Once you’re pretty good at what you’re doing, enter photo contests! In general, they have huge cash prizes for winners, and you’ll never know how your work is perceived in front of a jury. Maybe your passion will bring about a 6-figure prize.
