HS competition- I get it. You are young, you are racing your peers, everyone is trying to carve out their niche, find an identity (The Runner), This stuff is all still new, super exciting. I see why kids (and some adults) put too much into it. It seems super big and super important because.. everything at that age feels super big and super important. It's an age of exaggerated expectations, feelings, and emotions.
College- for the vast majority of us this is as high of a level of competition that we will ever see. A paper thin percentage of us go on to post collegiate running. THIS is where it is VERY real. This is where you are the age, you have the support, and you have the competition to truly see what you can do. Go all in?? HELL yeah. Be disappointed with a bad performance- YES!
Unless you are getting paid, everything after that is trivia. If you think anyone will think any more or less of you because you did or didn't his that time at Boston, or BQ, or whatever... you aren't thinking clearly. You have lost the ball.
Believe me, I would get super juiced up over my goal for the Fall, or some big race etc.. but, I did keep it in perspective.
