Actually, Cliff, you have touched on a good possibility there. Alternatively, some of my friends who sold out businesses or Directorships have gone back into the field part time, having some fun (in a business field they know well and are good at) and making some spending money as well, taking breaks to go on trips, etc. And it keeps them in touch with those business friends they like (ignore the others).
Or, Pete, you may wish to simply move on to other activities altogether. It's your call. At least you live in a cheerful climate, unlike the poor b*st*rds in the UK or South NZ, for example, where the skies are grey and you spend all your Super just trying to keep warm now that you are home all day.
