Man, I feel ya—but if you feel this way about solopreneurship, Chris, do not, and I repeat, DO NOT start a business, even a small one!
Running jits and MMA events have been the biggest headache of my entire life. They are much like what you have described except worse. In fact, I am now thinking of putting events on hold to focus on my solopreneur career. Funny how things work out hahaha
