I saw a TED talk once with a similar message - some guy talking about how there are no good jobs, there are only lousy jobs and great jobs, and you should shoot for the moon and try to get a great job, and how you shouldn't let your kids be your excuse for settling.
What I don't get is, when did choosing to focus on being a good parent become "settling"? Is it so bad to choose the dream of being a great parent over the dream of being a great comedian? Seems to me that the accomplishment of creating and raising a happy, healthy human being is pretty damn impressive too. Not saying it's not okay to pursue both dreams, just saying I don't think choosing to create life constitutes failure.
People always talk about dreams like they're some pot of gold, that each person only has one pot of gold, and that anything less that getting to the end of your own personal immutable rainbow is failure.
They sold us on the idea that we'd grow up to become astronauts or actors or athletes so long as we believed in our dreams. But not everybody gets their dream, no matter how hard they believe. Otherwise we'd have far too few trash collectors and Hollywood would have to annex surrounding counties to make room for all the movie stars. Seems like a generation ago, there was no shame in dreaming of office jobs and white picket fences. And now it's like it's the moon or nothing.
Thing is, dreams are what you do when you're asleep. On the way to the end of whatever rainbow you're chasing, might be worthwhile to open up your eyes and see the dream you're living on the way.
