I can make the working full time for myself work, though. I have a plan. Tomorrow I'll have some time to work on that plan.
A plan makes all the difference. It's like budgets in finance. Want to be rich but living from hand to mouth? Have to start with a budget. It can suck. Adding up expenses and subtracting them from income sometimes points out just how far we're in the hole, but you know, you're in that hole whether you know it or not. I'd rather know it. From there it's just a matter of figuring out how to work with the income you've got and then formulating a plan for decreasing unnecessary expenditures (sometimes that's impossible if you've cut to the bone already) and formulating another plan for increasing income if it's needed (usually it's needed but not always.)
Before I can work totally freelance I have to (on average) have an income of my wages plus benefits. The benefits are the tough things to match right now. I 'make' more in benefits than I do in wages.
But there's that number, and so I can set up a plan and adjust as needed once I put that plan into action. You'd better believe step one is not quit my day job. Good thing I (mostly) like my day job! Step one mostly involves using my free time to the best of my ability, while maintaining sanity. I had a sanity day recently, so tomorrow is a work on my self-employed job day. If I can get eight solid hours in, that would be good. Holiday shopping doesn't count.
Have you got a plan for your wishes?
