One should think about their skills, hobbies and basic daily habits as well. Do you like to cook? Be a personal cook or dinner parties. Baking? Make wedding cakes or cupcakes for weddings/special events. Do you enjoy cleaning? Trying going to banks/repo companies and ask if they are in need of a repo cleaner or market yourself as a all-around cleaner. Know how to mow a lawn? Get paid to do it in your neighborhood. Sell products from large companies – Jewelry, Scentsy, health and home products, etc.
Don’t let that stop you from starting a blogging business. There are lots of very successful bloggers out there – we’re talking 5 and 6-figure-a-month levels of success. What you absolutely must avoid doing is starting a blog about “how to be a successful blogger.” How can you do that when you haven’t achieved any success yet yourself? Faking it until you make it is not a business model we’d advise anyone to follow.
