I was beginning to woder where you'd gotten to. Now I know. I've worked the 40 hour workweek. I've worked the 80 - 100 hour workweek. I stopped about 6 years ago and never looked back.
For me, it was just too big a toll on my health, especially mentally. My anxiety was through the roof, my insomnia, which I've always had was awful and honestly, it felt like I had no life...work, kids, cook, clean, toss, turn, repeat. And the worst part, the more I gave at the office, the more they wanted.
I was lucky, I was able to afford to walk away. Our income dropped dramatically, but really, I don't need a lot of money. I didn't have a huge mortgage or car payment. I don't give a shit what "the Joneses" think. As long as I have good food, a roof over my head and can go travel a bit from time to time, I'm good.
Looking back now, I don't know how anyone does it, except that they do because they always did, if that makes sense. it's way past time we began to rethink work.
