re: What’s the easiest, most stress-free way to make $30,000/year as consistent income?

I think you're going to have to ask yourself, "what is stress free to me?"

Doing nothing for several hours per day would be stressful to me.

I like Baldona's idea of buying a machine and renting yourself and it out, but honestly, that's only stress free as long as the machine, the truck and the trailer aren't broken. And as long as you don't break a homeowner's gas line.

Big chain retail seems about as easy as you could get, and only as stressful as you let it be.

Best of luck, and see ya Saturday night Tiger Bait!
