Well MS, you probably have me nailed as one of the older, snarky posters. I'm really not far past that stage, and eight years ago, when they "identified" QLC, I was 31. I think my generation, Gen X, had it too. In fact, many generations had it. Flappers, swing kids, flower children, etc. I think Gen X had it to a higher degree than preceding ones, and Gen Y has it to at least the degree we did.
I think this ties in with Kunk's thread on the rudderless.
No grand answers from me though. You either eventually get some direction or you don't. Not saying which is better, as long as you can support yourself, I say travel the path that suits you.
One observation though: when I stopped seeking anything other than a pay cheque from my job, life started to make more sense. Sure, sometimes work will make you feel good. Keep that secondary though and remember you work for money, not some touchy-feely aim.
Wow, I'm rambling here, but I can tell you the age of my QLC was 24. Neil Young. Old man, take a look at my life, 24 and there's so much more...
30 was tough too. Decided I needed to kick things into over drive. I did, and I'm happy I did.
