Sounds like its not worth it to be honest. Unless you don't need money and you do it for fun.
It's really not a terrible living considering you can knock out 15-20 food runs, or 30-35 parcel runs in a day at the rates I mentioned above, if you're good enough. I'm certainly not well-off by most standards, but I'm definitely not uncomfortable, either. And it's way better than being in an office all day, which I've tried previously.
that would be the only reason I'd do it, I hate being in the lab/office all day. But with marriage, a baby, 2 dogs, and supporting my parents....I have no choice for now
If you're happy, then that is all that matters.
