I want to hit on something else, though: the ideas of "dream job" and the ideas of "self-improvement".
I sort of think that it's how you look at it. I don't think guys like Mark Cuban or Richard Rawlings worried about "time for school" or "dream job". They just sort of did it. And I think you have to be honest with yourself about what your talents are and what your interest is. If you're 4'3" and missing a leg, and your passion is "basketball", what does that mean? Are you going to be a starting center for the NY Knicks? Perhaps, but more than likely, perhaps not. But you can be a photographer, or announcer, or work in the front office... it's how you play it. My "dream job" is probably "rock star", but my skill set is in thinking strategically, and negotiation. So I focus on that. But I've been lucky enough to do those things for companies that gave me a taste of the thing I'm passionate about. I used to live in Burbank for work; I could (and did) hang at the Rainbow if I wanted (sat next to Ron Jeremy and shot the shit one night. Great guy, but high as a kite and didn't smell very good). I worked out of 30 Rock for a short time (not on air, but I've stood on the Saturday Night Live stage).
My son's passion is mechanics. So he got an associates for auto mechanics, and works as a tech - no one's dream job - but joined the Army to work on helicopters. Gets to work on possibly the ultimate mechanical engine. And now he has some scratch to flip cars in his spare time.
I don't suppose that everyone who is complaining about their lot in life is just sitting on the couch playing video games, but I do wonder how much thought actually goes into the process, and how honest with themselves those people are being. My daughter is an AMAZING artist. Her cousin is a well-known fantasy artist - who has done work for Disney among others, and has an impressive array of album and book covers - and says she is probably more talented than he is, if not as technically adept yet, but she has ZERO discipline. So the idea of her being a successful freelance artist is probably not good. But we talked and she got into cosmetology, specifically makeup design, and while she's still got zero motivation, and has a hard time getting to school, she's getting a taste of what's out there. She did a fashion show, and some movie makeup (bullet holes and cuts and stuff) and was fascinated.
Personally, I think there should be more of this kind of discussion in high school and college. No, not everyone can be this - the world needs janitors too (and no knock; that's still the best job I ever had) - but there are people with the temperament and skill set to be janitors. To some, that is their dream job.
We're talking here about "changing mindsets", and some of the talk is transcendent change. Well, we need at least INCREMENTAL change. We need to start thinking about our careers as something proactive and that we can manage. We have to start being more "macro" on our careers. Or, if we're not willing or capable of doing that, we have to be honest with ourselves. If we're going to limit our careers to 37.5 hours per week, and we're not willing to move, not willing to "give up our weekends", not willing to put our pay at risk (performance incentives, etc.) then we have to accept that we are in effect saying we're not willing to be more than what we are right now.
