Linze1106:To "live" is to buy food, pay rent and all your bills and have enough to spend on occasion.
My mortgage is a tad under 5K a month, so I'd have to say no, you can't live off of what a DM makes. I doubt I'll ever draw a dime from my work as a DM, but I will have every piece of gear I desire, do the dives I want to do and be involved with the greatest activity I can imagine to the extent I wish.
When I did this job as a kid, my rent, fuel and food were part of the pay and I didn't need much to live. I didn't have much, but I didn't need much.
