Learning to never listen to PMs sounds like the opposite of being humble
I thought I needed to earn my place and tried very hard, but slowing down and going home at the right time regardless of whether the thing I was working on was done or not, would have been smart. They placed a lot of pressure on me to produce perfect code at the same rate as all the java devs based on the assumption the assumption their job was harder because it was backend, but the tools and parameters of their work were wildly better at the time, and I had undiagnosed ADHD.
So, I'd be protecting my sanity more and telling them it'll get done next week instead of trying to fit one more thing in because "it's just a button" or whatever.
