I think when looking to work from home it is important to consider any skill sets you may have that you did not previously use for your career. For example, there are plenty of childcare opportunities that you can work toward qualifying for even if your previous career was something corporate, such as marketing or finance. You may just find something you love! You also could find something you never want to do again, in which case, at least you know:)
Bloggers are typically people who enjoy a particular topic and enjoy writing about it on a semi-regular to regular basis. If you have something you are passionate about, or are an expert in a particular area, you can consider starting a blog. Blogs are a great way to: teach people about a particular skill, entertain, or share about life experiences.
