Plenty of adults choose to work hours over quality. Lawyers fit in this, and that's largely because a lot of their work is billed suspiciously, a lot of their work is very low status (so while highly paid, they have to work around client schedules), and because a lot of their work is dull as hell.
If you're constantly pulling 60 hour weeks (about what you have to pull to bill 40 honestly), you're likely delivering what I am pulling 35-45 hour weeks, billing 25-35, but at a higher cost to your family/health/rest of your life.
That's not adult. That's slavishly burning yourself out in your early years.
