Nearly everyone you work with is trying to do a good job. Nearly everyone you work with has a different idea of what a good job is than you do. Time spent treating them as hostile actors or assuming they’re just behaving randomly is a waste. Time spent understanding what they consider good and why is intensely valuable. Plus assuming your coworkers are trying to ruin your life tends to make you act like a salty asshole.

Don’t nit pick things that don’t affect the outcome. Correcting somebody’s terminology or recollection when it doesn’t matter just derails the discussion.

Delayed feedback is just professional grudge-holding. Tell somebody what you think while they can still do something about it. Don’t let it bounce around in your head, don’t let it dilute over time.
