I'm already unfazed at that part and don't care.

What devastated me this week is that I was slogging so hard for the past several months trying to deliver on what I was asked to deliver on, only took 1 week of PTO out of the 4 weeks I have saved up, spent nights and weekends trying to honestly solve multiple high priority yet HARD problems that 500 other engineers in the company couldn't solve, I'm making good progress on a couple of them single-handedly, yet my manager, who just came back from 3 weeks of vacation just gave me a performance review saying I am not meeting the "bar" for my level and need to do more cross-functional work and amplify my "impact". He's going on vacation again next week to watch the eclipse.

Fuck this. I want to travel, I want to enjoy life. I used to chase eclipses, too. I tried my best, all I ever get is "what you are doing is not enough". What the hell IS enough then? I already don't take vacation and don't exercise, I've put on 7kg of weight since I joined, yet you told me THAT is "not enough". Should I stop sleeping and eating?

Change priorities all you want, honestly I really don't care, and I've dealt with customers too, it happens. Just don't tell me I didn't get anything done. Recognize the fact that I tried hard every time you changed your priority, and I only had 2 months out of 8 to work on your latest priority, and calibrate your expectations to 2 months of work, not 8.
