Wow that imagery is powerfully sad. Corporate culture and its structural constraints makes monsters of all of us.
I didn't mean it to be ;) I'm an optimist at heart, honestly, and I'm not sitting here feeling I've wasted my life or anything. But there are some things I wouldn't do again if I had my time again, and working hard for unappreciative, self-centred people is one of them.
That's a bit of a luxury, you don't always have that choice but on the whole I agree with the idea. I'd re-phrase it to don't work for assholes if you can avoid it. I'm fortunate enough now that this is a rare occurrence but even now every now and then a deal goes by that is financially too sweet to let go and I still take them. Last year this happened once, the previous 3 years not at all. So unless you're totally secure in your finances keep that door open a crack.
Good to see you on this side of the line after two heart surgeries.
If I could go back and tell myself something, or if I had kids to advise, this is the essence of it.
Once you've got your basic needs met, anything you do to enrich your character is going to make you a more compelling person. Don't squander your 20s and 30s. Take advantage of opportunities that present themselves, because it's a lot harder to cultivate new opportunities from scratch.
GP, if you can actually afford to pick up and try something new, you really ought to do it. It's so easy nowadays: pick a city and spend two weeks at an Airbnb. If you like it, stay longer, and if not, go back or go somewhere else.
Remember that wasting time at 20 seems OK, wasting it at 30 will make you nervous, and if you're still doing it at 40, you'll wonder where all the time went. It really happens surprisingly fast - at 29, you feel young, but a short decade later, you'll fret about being "too old" (which is an illusion, but it takes a while to know that). Don't worry that you'll mess up your career or anything else by taking some time to do something adventurous. Pretty much whatever you do, you'll look back and thank yourself for stepping out rather than hunkering down.
BTW, as for "work is very intense" - it probably isn't worth it. I burnt out once after a few years of very intense, very committed work. I wasn't better off at the end of it and nobody says "thank you", not sincerely anyway. And after you leave, the waters close around you and it will be like you were never there. So if you're not enjoying it, maybe it's the kind of bullshit you can do without?
