Er, maybe I'm missing something but couldn't you be doing productive and relevant things with your time right now? You have a home, a computer, and presumably at least limited access to transportation.
Haha, I wish. My home is in the middle of nowhere, and my parents specifically chose it for its scenic location. This probably seemed like a great idea before they had kids who aspired to have a social life and before the internet and cell phones were common, but now it mostly just functions as a prison. I don't get cell phone reception, the only available internet connection is 18k, I can't use the land line and the internet at the same time, and we can't upgrade to satellite internet because the trees in our yard are "blocking the signal." I do have a car, but I can't even use it to visit friends because most of their families moved away years ago (I don't blame them). My only real escape is occasionally revisiting my former college, but doing that regularly isn't an option because the gas and maintenance for my car would make it prohibitively expensive without a job. Alternatively, having a job monopolizes enough of my schedule that I'm simply not available to leave when it's convenient for my friends in Oswego.
This isn't to say that nothing has worked out in my favor. I'm thankful that my parents are allowing me to stay with them rent free, and I'm happy to possibly be beginning a job working with people with developmental disabilities soon, but it's not the kind of thing that I anticipate spending the rest of my life doing, or even the next five years for that matter.
You could at least be volunteering somewhere.
I already volunteer with the BSA and I do educational presentations about reptiles.
If you really lack the motivation to do anything productive with all your free time, I don't think you have much to worry about regarding the opportunity cost of having a job, and if I may presume to say so, you really don't sound "destined for greatness" either.
What a short sighted thing to say. Clearly, I'm not currently in a position to be doing these things, otherwise I would be. I'm not concerned with your criticism of how qualified I seem to you either. It's evident to many in real life that I have a lot to offer and the fact that I'm good at pretty much everything while receiving so little satisfaction from most of it is certainly evidence in my favor. I was routinely understimulated in high school and college just like I am now. That doesn't mean I'm unambitious, it means that I'm uninspired, possibly as a result of not being challenged enough.
So what exactly do you define as this "greatness" you feel destined for?
I have yet to figure that out, unfortunately.
