A cool career is just that. You're gonna work all the time and be poor. If you're ok having your life be about work, then go for it, but the happiest people in the world aren't working all the time.

I was fairly successful for 7 years in television production, but realized that I'd rather work 9 to 5 and spend more time with my friends and family doing fun things. I became an accountant and found happiness.
