Do you think it's more likely for a first-time entrepreneur working on SMB SaaS to find success with something that's not "fun"? I mean working on something fun is ideal, obviously, but the fun stuff is usually going to be much harder than building a simple web app. It will be nice to one day afford to work on something fun, but for now I need something that pays the bills.
