They say that you should be passionate about what you do-- but more, follow your passion in life.
So, if I was going to do that, I should be a musician (drummer/pianist) on international tour for half the year, and the other half doing shows where I live, in Los Angeles. I'd be doing some kind of philanthropic work to help people out in need whether it's feeding the homeless in a soup kitchen, building or painting urban housing, or helping with disaster aid efforts.
But, I'm not doing that with my life quite yet.
I work a 9-5, and try to make this startup work in the evenings and weekends. In my past I've done other things in my free time, like bartending/waiting tables at a sushi restaurant, been in a corporate rock band, and enjoy my social life. It's actually quite selfish, admittedly.
But none of these things are what my passion is, but they keep the lights on.
I was warned not to make my passion my vocation by my old sushi boss, because I'd get tired or bored of it after awhile. While I agree to a degree, I think it's totally possible to be passionate about something that is not necessarily your passion- but somehow tie it in.
I guess I'm still trying to figure it out.
