Each person must make that determination for themselves, of course.
Trying to find THE BALANCE is, in my opinion, the challenge for all of us.
I think if you feel you are working too hard you start by at least taking weekends off. Then graduate to working a 4 day week.
But I also believe in MAKING $$$ so you can obtain total financial security one day where everything is paid for essentially and you can dictate how much you work and how much you don't.
I have a friend of mine who retired early and he has been under financial strain for the past few years and had to go back to work for less pay....a good lesson to learn by for some. I already knew he made a mistake when he announced he was retiring.
I am VERY fortunate that I LOVE what I do for a living. And I'm self-employed. I see myself doing what I do almost forever - but scaled back more and more as I age.
I also believe when certain humans "retire" they start going downhill. Depends on the circumstances, of course, but that's the trap some fall into, I think.
