Hey, I'm glad you feel so enthusiastic about running. Really, I am.
But for me, I expect very little out of it except that it's going to be an as uncomfortable as I choose to make it. But it will be uncomfortable.
And with low expectations, I often find some small measure of fulfillment and satisfaction out of it, maybe a little surprise that I was able to muscle through it, and often some glimmer of hope and pride. And after doing that as long as I have, I know that I just need to get out the door and start, letting the run come to me, and it'll be worth it.
That's what has worked for me for a really long time and through a pretty rough injury.
EDIT: re-reading my original post, I have to admit that it was meant to be a little snarky in the hope of striking a little humor.
