Much as I would like to, I don't think I could handle the stress. Keeping my own hours would be nice, but trying to attract business and dealing with taxes does not sound nice. The pressure of being solely responsible for a business would probably break me in no short order...it's not as easy or glamorous as people like to think it is.
I suppose I've always had dreams of being Patreon funded or something, but I don't have any marketable talents...and I suppose that's what it all comes down too. I'm not confident enough.
