I'm 28, and about 2 years ago, I quit my corporate job for a much less secure one, that made me not feeling like I was selling my soul.
So far it's worked out. No, I don't have medical insurance any more, and my paycheck is less steady.
But I also don't have to get up at 6:30, and shower and shave, put on a shirt and tie, and get bossed around by rich people.
I haven't taken a big trip yet, but I COULD. :)
