I think the author had unrealistic expectations from working at a large company.
He expected doing something meaningful that will change the world. He expected to be applauded like a hero for his efforts.
But things don't work like that.
If you work your ass out, don't expect more than a pat on the back. Managers won't care about your efforts, your mental state or your sleepless nights. They care about looking good in front of their superiors.
So it's better to do just that is expected for you, enough to get a good evaluation.
If you come out with a brilliant idea that might help the company a lot don't just do it. Find some allies in the higher hierarchy, explain to them what is their advantage, do a POC or MVP, then let the top management know in a public meeting. That way you get a lot of credits and applause for doing great things for the company and fighting the good fight.
