well i've always been sort of self-employed before, projects here, projects there, wrote a book, just had jobs on and off - but it was never a thing i did as 100% like now - which is a hell lot scarier
But I will say that it's hard to imagine that a startup will be successful unless you are emotionally all in, and that quote failure is not an option unquote. Doing stuff on the side never really made sense to me, other than as a bootstrapping strategy. The anxiety and stress, if you are able to channel them productively, are amazing sources of energy and focus. Good luck!
