no steady flow of income from a full-time job? What do you do then?
Well you do what you would normally do, get a job....that pays bitcoin. It's not complicated and actually when using bitcoin it's easier to understand than in the normal economy.
In normal life you try to "get a job" and you "get paid" for "working", this is how most people see it. But actually you get paid for doing something for someone that they think is valuable enough to pay you for.
You COULD just try to buy your way into the bitcoin community with outside cash, but why bother, why not just work for someone who will pay you bitcoin?
What can you do? What are you good at? Tell us? Everyone can do something, you must have some kind of skill that is worth payin for.
