>As a counterpoint: I also have ADHD and went out on my own. Without oversight and managing I performed absolutely terribly. The company I started produced nothing and I ended up worse off after the experience.

Same. Was absolutely not for me. Some ADHDers go this route successfully, and especially if you can hire an assistant to handle some of the tasks that require more executive function, but there's plenty of us for whom it will just be a disaster. I think it's important for anyone thinking of going this route to give it a try and find if they're one of the ones who it does suit, but have a clear criteria that will allow you to evaluate how it's going for you and trigger an exit in a timely fashion if need be.
