What clarified things for me while reading it was coming across this line: > Well, I AM actually stubborn!! But if the metrics had shown that BATCH was worse, I would absolutely be the first to change my mind. He's self-critical. I also think he's only right about being stubborn in its original meaning (untameable) rather than the new colour the word seems to have (unwilling to change despite evidence). What happened here was an NHL player joined a team thinking it was another major league team, but it wasn't even college ice. That's fine, but his mistake was not just leaving for a different team. If you come into a team thats slightly beneath you you can raise it up to your level and change peoples careers / lives for the better, but getting too far off just doesn't work. You're way too ahead of them and you're new so they don't trust you or want to listen to you. Just move on to a more pro project.
