How much net income can a carving machine earn in a month?

Water and electricity costs 100 ~ 200, rent 400, accommodation at least 400 ~ 600, and some tools and wood. In my opinion, I can earn about the same money as I do now, maybe less, but I need pressure to motivate myself. If I don't do it, how do I know if I have earned it? Give yourself some confidence, come on!
