Literally every time I had a 3-4mo 80-100hour crunch it always started out with "we're going to push for a week or two" which just transitioned into "just one more week" for the next 3 months.
Also, shame for celebrating a crunch. You may have enjoyed it but there's a high likelyhood someone else went along just to not "rock the boat". I don't care who you are putting in more hours puts stress on other parts of your life.
I just don't understand how that industry has their head up their ass from top to bottom for such a long time. There's some interesting problems in that space but after my 6 years I'd never go back.
