Nooooo how dare you dismantle the assumed meaning of my next motivational poster? I was finally going to use the fighter-jet background. Or Muhammad Ali. It would've been so awesome. Can't do that now, that I know the truth. Why did you drag me out of the cave? I never asked for that!
Anyway, thank you for the further interpretation and prolonged verse. It is indeed easy to take this part out of context, and use it for self-adulation. Though I think it does work the other way, too. That something makes all the difference because of the road taken - but not good. Probably what the chap that Frost wrote the poem for was like.
