Yeah that resonates.
It just feels inefficient though to me a bit. There's been plenty of times in my life where I've been in "grind" mode and sleeping less, eating poorly, not working out, etc. in order to be "more productive".
But in all cases, looking back, I feel like I was really just spinning my wheels. Like if I were to take those months here and there and work 1 hour less each day to just eat a salad, take a walk, sleep more -- I feel like I'd probably have made better contributions to our goals.
Hard to know since it's all a bit of a retrospective exercise.
