I see self-employement as the most plausible means for you to support your family. Nothing else really feels very good to me. There is a sense of that really working for your personality (being self employed) as opposed to working for someone else. I think the key here, is not so much about what can bring in the most money. It's what can you do that you are passionate about and help support your family through those means. Living to work is not the right path for you. You said you know what you want your life to look like more or less. I encourage you to go with that. What you enjoy doing, find a way to make that "work" for you. And for right now, stick with what you got going on. This feels reasonable to me and I keep hearing, "don't fix it, if it ain't broken"
I really hope that helps, and I'm sorry it took so long. I was just having a really hard time dialing in. But that can happen sometimes.
THanks for your question!
