Job, house etc I did a similar thing although the circumstances were a little different.
In terms of emptying, skipping possesions, That was the biggest wake up call.
We must have spent thousands over the years, and it makes you realise how you fall victim to consumerism and ' must haves' when you actually dont need them at all. I literally skipped thousands of £'s worth ( start your sale now)....when the house sells everything happens at a tremendous speed.
I took on some storage to stock things real close to my heart, for example grandparents writing desks, Motorbikes etc.
It costs me a small fortune, but at least i have a few bits and bats and the idea is to bring out of storage when I settle.
Like yourself, i work on the basis there is no guarantee I will retire, and best to do it whilst i can and have my health etc.
Finally you are spot....'' NIKE''.Just do it !!
Good luck
