Seriously…why don’t you just get a “regular job” like most folks?
If you can’t answer this question, you shouldn’t be in business.
As a self-employed creative professional (I like the term “self-employed” almost as much as “freelance,” which is to say, not at all), what you really are is a small businessperson. To be a small businessperson, a successful one that is, you need to believe completely in your product and yourself.
If you can’t say why you’re not working for someone else, then you shouldn’t be working for yourself.
