Explore dozens of DIY portals (such as DIY.org, DIY Network, Instructables and Mahalo) to get business ideas on how to earn a healthy side income just by showing others how to do the things you love. You can also sift through the countless ad-supported YouTube channels that teach just about anything from guitar strumming to 3D printing.
