I retired from medical engineering when I was 47 because I decided that time had more value than money.
The common expression “time is money” is ludicrous. Time isn’t money, it’s time and it can’t be bought because it’s not for sale.
So I developed a lifestyle where money isn’t that significant. If we were to become financial destitute tomorrow it would change very little in the way we live.

I retired when I was 56, completely burnt-out trying to achieve purpose through work (a lie which isn’t even paid lip-service these days); now I’m approaching 60 I think I know what not to do anymore …

I know, excellent way to say it “trying to achieve purpose.”
