One of the most beautiful and exciting qualities about blogging is that you can create a blog that deals with any subject area that you are either knowledgeable or passionate about (and preferably both!). You can write about personal finance, careers, real estate, getting into business, technology, cooking, travel, personal health, or just about any topic you choose.
Nothing beats teaching more novice learners about your passion, hobby, or craft as a business idea (that's a common theme here). 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.
