Yes, like literally all. For example, from what I know about translation business in the US, a newbie translator spams like 100 addresses with his resume daily (perhaps 5 out of it will bring any return). That’s fishing for customers rather than employers but still. The market is smaller where I live but I remember hitting 20 daily and much of my week being devoted to preparing free samples for evalution.
Hard work is worth it, as is experience that comes from it but I doubt whether 80 hours a week leaves enough time for a normal human life outside of work (I already have doubts about 60 hours unless commute time is short). If you get to socialise at work, you eat meals with your jobmates or clients during a break and that’s fine with you, and also your work coincides with your hobbies, then you can be fine. But working from 8 a.m. to midnight, presuming you don’t work on Saturdays doesn’t even leave you with a healthy minimum of sleep (24 minus work minus commute minus unpaid meal time minus shower etc. will not leave 7-8 hours for sleep), let alone any time to unwind. What about spiritual development, what about spending time with family… there’s only so far you can go working 80 hours a week. If you keep doing that for years, you won’t have a life and you will damage your helf (physical and mental). I realised that early on and decided I wasn’t going to put in 80 hour weeks unless in isolated cases (I have worked 40 hours straight, for example, so it’s not like I don’t know hard work…). Also, in some jobs, being working for 10-12 hours straight can lead to disaster, let alone 16 hours (psych problems start happening and I’ve been there done that). Accountants, translators, lawyers, just can’t afford being permanently underslept and chronically tired. Mistakes are too costly. There’s recently been an estimation of how much US economy loses due to mistakes made by overworked workers (profit is not effectively maximised by making the same people work double time). I’ve seen myself what dumb mistakes brilliant people can make if they don’t get sleep. The effect it has on family life through the personality changes, burnout and whatever else it can lead to (including heightened aggression, sometimes paranoid fears or combative mode, loss of empathy etc.) is just too much.
I actually believe that in many job lines, you’d ideally work under 8 hours so that you could stay healthy, stay sober (3 nights without sleep is comparable to being drunk), make sure your family isn’t falling apart while you aren’t looking (you don’t have kids that don’t know you and spouse that only gets to sleep in the same bed and maybe say hi before or after bed time), keep up with continued education (e.g. follow the press and monitor academic progress in your field, attend conferences, courses and seminars) and so on. This is a bit different for singles but singles will stays singles forever if they work 80 hour weeks, as noted by a young female lawyer from my last law firm.
