Tons of different hobbies can make you money. Here are some of the most profitable categories:
Skill-based: Hobbies like photography, writing, editing, audio production, voice acting, dancing, etc., can be turned into service-based businesses.
Product-based: If you're into knitting, sewing, jewelry-making, pottery, and painting, you can sell your products on online marketplaces like Etsy.
Teaching: Hobbies like yoga, meditation, piano, and language can be turned into a business where you teach others how to take on a hobby or learn a skill.
