Hardly. I've worked up to three jobs at a time while carrying 15 credits as a graduate student (9 credits is considered full time, BTW). Have put in an easy 10 - 12 hours of work a day for weeks on end. Have had sickness as a direct consequence of working too hard for extended periods of time. Have traveled for day gigs by being far away from home for extended periods. Have played hundreds of gigs and never missed one, used a sub, or had a date moved on my behalf. I'm pretty much a classic overachiever. But hey, you'll welcome to make assumptions about me. I can send you copies of my resume and CV if you need proof.

Cute ad hominem, though. You're welcome to go around to anyone who lost their day gig to an economic recission and call them lazy. The world's a little more complicated than any Randian notion that the cream simply rises to the top on simple principle that it's the cream.

It's not an excuse, as I'm sure you'll spin it, It's just reality.
P.s. I should also mention that I'm actually not in disagreement with you about learning new skills and adapting to new labor trends; there's no point in sitting around bitchin'. However, as I mentioned in a previous post, I do career development stuff for my day gig. If there's one thing I've learned from dealing with this stuff on a daily basis, it's that adapting to labor market trends doesn't happen over night and everyone's situation is different. Also, successfully adapting to changes in the market gets increasingly difficult as you...you guessed it...get older and closer to retirement age. My entire point is that the simple, "don't like your job situation, simply change it" mindset is so far from reality that I find it to be aburdist comedy.
