I say know your goals, and then build a career around those goals. Otherwise you're inevitably going to sacrifice non-deliberately one thing or another from a given template.
Like, here is my Grand Plan.
I wanted something that was inter-disciplinary, and helped people, and made cool stuff. Like most of you here I also wanted to constantly learn.
I fucking cried when I saw this: http://www.miqel.com/fuller_design_s...ce_basics.html
There aren't a lot of people who have that job description now, because like being a Renaissance Man, it's more of a lifestyle than anything. But now I knew it was possible, in some shape or form, Buckminster Fuller being the epitome.
So the way I'm doing it is that I'll be a CADS, but not constantly. I'd try to maneuver myself in most industries so that I can design products they want/need to fix an ecological or poverty problem, and that I can get teams together to do this based on my contacts. Very interdisciplinary, you'd travel to survey the resources in an area etc. It's hefty, but I've seen the promised land.
But then you need fallbacks. I got inspired by Tim Ferris' Four-Hour Workweek to try and set up a passive income, somehow. I'm guessing video games. Enough said.
And make sure that your hobbies contribute to your income, even if its only mildly. Obviously they should be open enough and money shouldn't be that big of a deal at that point (either due to your financial security or your willingness to forgo some pleasures), as otherwise you'd eventually lose enjoyment.
So basically my financial life will take three tiers: the first tier being a commission job, which could occasionally get relegated during my education (ultimately my education would fuel this dream, so this is OK); the second tier being a passive income job, which demands minimal micromanaging while still pulling in moolah (this is fallback if the first goes under; and finally a hobby-job, which is the ultimate
And if this is too much, outsource to India (thank you Tim Ferris).
I guess what I'm trying to say is don't be afraid to work, not when the best pleasures in life are free (books at a library, which can be requested for; the love of a girlfriend who knows your going somewhere etc) and anything else is basically a bonus. People can and will bear a lot for their dreams and we should be no exception. It's also OK to have a gazillion dreams because you can basically go anywhere, not regret it, and if you do switch to another one. Having that passive source of income and a hobby you're always interested in fuels whatever the first tier job is.
So good luck.
PS All of this is moot because I'm 18 and failing high school
