Sometimes it's also better to lose a battle in order to win a war. For example, I once thought a certain feature was useless and not worth the effort to implement. I knew however that if I chose that hill to die on, it would lead to a lot of resentment -- "if only we had built that feature, we would have X". I decided to concede as this was not a big feature but, like I predicted, the feature was useless. This now put me in a better position for the future where I could draw on this as a lesson for when it truly mattered. Whenever we would be at risk of getting distracted by some much bigger useless feature, I was able to point back to that experience to bolster my dissent with more credibility in a way I might not have been able to if I didn't pick my battles.
