Of course! Millions of people around the world are taking to work from home jobs - instead of the traditional 9-to-5 jobs. Blogging is one profitable online business that has very low start-up cost. You don't even need to quit your full-time job to start a blog. Part-time bloggers all over the world are making money blogging (up to six figures), as a side-hustle each year. I started my blog the same way too and eventually monetised using affiliate marketing and advertisements.
