We all after 30 more or less in your position, if don't have some spare capital, like father's house (as in Ghost busters, btw, old good cinema).<p>Unfortunately, this is not good position, because from $600/mo to something considerable for family life in US, may be long path, and not cheap, and not predictable.<p>I don't think you consider moving away to some cheap place, so answer is simple - keep your day job.<p>America is country of freedom, so you could continue your side business, and continue grow slowly, but until it will grow much more (I think about 10x at least), it will not become attractive for much investments, and you should not consider it as your main priority - now your main priority family and day job.<p>BTW, $600/mo is considerable amount for 3rd world countries, and this could be real solution, but it could be not easy, to hire people abroad.<p>Sorry, life is hard. I believe, if you will see old good cinema, this could make things looking softer and warmer, to accept.<p>And tell me, if you want to talk more.<p>Thank you and good luck!
