Absolutely, Rob. And I'll go further than that. People reading "I have three jobs" might think, "Yikes, poor guy."  Nonsense. As you point out, he's just not working the right jobs. 
Then there's the sentiment that, "Yeah, well, he shouldn't HAVE to work three jobs."  Lots of advantages. I did it constantly--by choice--for about 30 years. 

Even in my toughest of hard-scrabble years (when I was over 55) I managed to feed, clothe, house myself, pay off a car and save money. Leads to some interesting employment, for sure (including concession bar at multiplex cinema; cashier at food chain store--good money, after 5 part-time years: close to $24 an hour--hey, and pension, too!)
