> some people always put in very long hours for some reason, complete with gulping down a sandwich in front of their computer for lunch. I'm not sure what gives them the impression they have to do it, since it's clearly not expected from our common higher-ups.
This is just how I like to work and approach problem solving. I can take breaks when I make the effort, but, when work starts, I rarely think about anything except climbing whatever mountain I find myself on, helping others at my company, or exceeding my own (or others') expectations. That intensity helps me think deeply and solve problems effectively.
There are people in my company who do good work but draw boundaries clearly and sharply. I respect that. I just love what I do and find it interesting and absorbing partly because I love the intensity of striving and struggling, constantly refining, improving, growing, and exploring.
My company generously rewards good work, too. That also helps; my effort never feels wasted, unacknowledged, or unrewarded.
