I have been a software developer for 30+ years now, and I have avoided working outside the 8-5 hours at every opportunity. I had bosses who very much chaffed at this, who were spending literally their entire lives working, and wish that we drones did the same.
I didn't, I just didn't show up if such a thing was expected, and made sure my work was good enough that they wouldn't think to fire me.
Now, I spent time with my kids, I stayed healthy and happy. My wife adores me for the time we spend together. The loss - nothing. I invested my income wisely, low risk, starting in my 20's, and am now sitting 9 million in assets and cash.
My bosses? One divorced, alienated from their kids, their companies sold and disassembled, and super sadly then contracting cancer because they could never give up their cigarettes with the level of stress they felt. They'll never get to enjoy the money from their sold company, they'll never get their family back.
Another, shunned by all their ex-employees, their own children (and grandchildren), suffering from the need to "get back in the game" when they're way past their prime, and when they were near useless at their job before anyway. But they worked all the time!
And another (years after I worked for them), fresh from a failed startup where they had invested all their money, and convinced their friends and family to invest, and having to lay off their entire staff after a failed pivot where they worked 24/7 for 5 years, going slightly nuts and now living in a commune in Massachusetts.
You get one life folks. I don't care if you're having the time of your life with your 24/7 job/startup you love so much. It's like taking drugs - it's great while you're doing it, but the repercussions come later in life. And they're awful.
