As a follow-up to my last post (and by the way, thanks for all the chiming in and the support on that one) I was talking to N last night about whether or not this kind of thing goes away. Whether the goalposts just keep on moving and getting bigger (or would that be smaller) as you progress. And my answer was that it does. For me, the next big one is selling a novel. After that it will be something else. The urge is always there to do better, make it bigger, make more of an impact in some way.
Then this morning, I read this post from Ty Franck about a recent brush with Hollywood, and I guess it sort of illustrates that point. There are different levels. And the one that he had a glimpse of (itself a different level from where he says he is) is like a different planet from where I am. A dimly lit spot in the sky, if that. Those are things I don’t even think about or strive for.
It helps to give you a sense of perspective.
