[ASAP]

While I am not remotely close to retiring age... from the people that I've met that have retired (outside of financial considerations), the only thing that I can say is make sure you have hobbies and interests outside of just working... and especially ones that you make sure you have enough $ to enjoy once you retire.

I don't know anything sadder than-

1) Someone waiting to retire because they wouldn't know what to do.
2) Someone retiring and going back to work later - part time or whatever.
3) Someone retiring and not being able to do anything they actually want to do because they can't afford it.

I know faaar to many people in the above 3 categories... in fact, I can say I only know one that doesn't fit in that category... and he a has a million hobbies AND quite a bit of $.
