There's a time on the mountain for me when I'm tired and maybe want to turn around. The same often happens in difficult projects (2/3 of the way in when the fun is over and it's just the shitty part of execution left). In hindsight, the time when I should have turned around (if it existed) is almost always later than when I started to want to. I've pushed myself farther than was healthy out of stubbornness and also given up when I should have gone on. But for me, when I wanted to stop was always before I should have. So I agree with his prescription somewhat. If it's not fun for you, that's a problem. But have those misgivings early and discard them. Once you're two thirds up the mountain, dig deep and use your reserves to finish. I agree with that philosophy because when I've wanted to give up and dug down and finished the thing (without hurting myself) I've always appreciated the achievement. I generally regret it when I don't finish. I do agree that if your pack is 20 pounds too heavy and you're exhausted yet hoping to do 1500m elevation that day, you really screwed up planning. At some point executing a shitty plan out of stubbornness is a shitty idea.
