I'm 53 and financially I could retire. I have a decent job that I enjoy some of the time, but also find at times frustrating and others boring. It gives me quite a bit of status, which I do enjoy 
I think the fact that I know I don't need to do it, doesn't help. Knowing you need to do it for the money probably keeps most of us going more than we realise at the time.
So I'm starting to seriously think about retirement, but where do you get that sense of value and importance, the feeling that you're needed from if not work?
I've done some volunteering in the past and whilst it fills time, I never felt it gave the same sense of achievement as worthwhile work, you're always just helping out rather than doing iyswim.
If you could retire young and fit, would you and what would you do instead of work?
