I think there's a difference in psychology - for lack of a better word - that makes some people have a much easier time managing the outflows than the inflows. For example, I know I have marketable skills - I'm a decent masseur for example - but I struggle mightily bringing in extra money with these kind of side gigs, despite finding them a lot of fun and not exhausting the way work is. I'm not sure if it's a matter of practicality or what, but whenever people explain how they up their income when needed, I don't get it. None of the steps explained seem difficult, but it's a difficult process to get through for me. Maybe the kind of cost-cutting I can do would be similarly difficult for others, I'm not sure.
