If you are burned out watch the talk "Pushing through friction" by Daniel Na. That talk inspired me and saved my job.
Thanks for the recommendation, talk was indeed banging: https://www.youtube.com/watch?v=8bxZuzDKoI0
The other example of the guy saying from the outside, their fix will only take 2 weeks. That's an estimate from someone who doesn't have the whole picture, if your asking another team. The resolution was to pester people and write up long docs to convince them its worth it. This is immediately adding on to your estimate of time.
This idea of friction seems like its more a question of trade offs and prioritizing work. Is it worth going through all this effort and context switching to try to see if this thing can be done. Is it worth distracting other people. I think calling it friction means we could possibly be undervaluing work that is prevented by this friction. Ill have to think about it more
