Still, I've seen many folks in esports do crazy workloads and get nowhere fast. So there's more to the formula than just pouring in more effort.
While I don't want to dismiss your extra effort as improving your results, I suspect that the value placed on your behavior by management may have been out of proportion with objective truth.
I'm also concerned with whether you were Defecting, in a Prisoner's Dilemma sense. Management always sets unreasonable deadlines as long as anybody agrees with them. Only when people are unanimous that this is crazy do they ever seem to back off.
Typical examples would be a client says "Oh no, our campaign that was supposed to start next Monday just fell through - we need a solution ASAP!"
or
"Our project is six months past deadline with no end in sight..."
For some, this is an unreasonable situation to find themself in. For me, I look at such situations as opportunities. The client's management is under a ton of pressure to fix things immediately and a lot of the internal friction that exists for the employees doesn't exist for me as an outsider. I'm allowed to stick my finger in the wound.
Still, you're absolutely right that management (and it's not in any way limited to the US - I've helped clients across North America, Europe, and Asia who all had the exact same problems) can be unreasonable. I wish I knew a good solution for that, but the truth is that there's a fairly small percentage of people that are actually good managers and there's an enormous amount of political nonsense where managers try to justify their own existence by carving out little kingdoms for themselves.
This is just nonsense and reflects a desire to dismiss the capabilities and accomplishments of others because they don't reflect your self-pitying worldview.
Chances are that the above poster did something you're unable or unwilling to do -- and the difference in outcomes is reflective of that.
2. Double income isn't necessarily that much income, if you're making 35k giving up sleeping to get 70k seems like a pretty poor trade.
Also, no, never. I would never work twice as many hours (assuming we're taking a base number of hours between 6 and 8) for twice the pay. You effectively earn less money (due to graduated taxes) and you have to give up all the creature comforts of life. Going from working 8 hours a day to 16 hours a day would drastically lower the enjoyment I got from life and probably end up killing me from stress.
I personally really enjoy working, and never felt that working 80+ hours was a burden. To be honest I actually look forward to getting up and getting to it most days.
With all that said, the growth I had just wouldn't have been possible on 40 hours a week of work. So I credit the long hours with the creation of a lot of the luck and opportunity I experienced in my life.
A personal bugbear of mine: your point is directionally correct but expressed incorrectly. Under marginal tax rates you do not earn less money. You take home less per hour past a certain point, but are still earning more overall.
I'd be a lot less bothered about people getting this wrong if it hadn't been turned into a political football in recent memory.
Because he sacrifices his health in order to make money.
Then he sacrifices money to recuperate his health.
And then he is so anxious about the future that he does not enjoy the present;
the result being that he does not live in the present or the future;
he lives as if he is never going to die, and then dies having never really lived."
