An interesting quote by Gail Blanke (from The Uncollege Alternative by Danielle Wood)
In our culture, we like to ask our kids, "What do you want to be when you grow up?" It's a question that implies a finished destination you're supposed to reach and stay at. It teaches us to think in terms of arrival. But the idea that we become something and stay it, that we "finish" establishing an identity, is a myth. In fact, you're this ball rolling forward, like a big snowball that just keeps gathering up more stuff on the way.
Life is a banquet, really it is. And most of us are starving to death because we don't see that it's all there for us to take. I think the whole trick is continually exploring what you're passionate about.
Your only real job is to have a fabulous life. That's it. However you define great and fabulous. That is what you're here for. You're not here to settle. You're not here to fulfill somebody else's dream. You're not here to have an OK-mediocre-"I got through it" life. It's to thrill you. So that you can have on your tombstone, "It was beyond my wildest dreams and I wouldn't have missed it for anything in the world."
