Depends on what kind of exit strategy you are talking about.
If talking about your living... just enjoy. My mom and dad are both 85, and they still every day ,if not painting the house, or starting another garden out in the field, they are buying houses and flipping them. And when they get restless, hell, dad starts up his GOLDWING trike and they just go like the wind.
If talking collections of militaria... Sell off every thing and go SPEND THE HELL out of it.
You start talking exit strategy, etc. man, that gets to you after awhile, depression/worry/ anxiety/all will get in your head. I get into trouble daily because my wife/kids/friends all want to talk about the past!! WTF??? I think about tomorrow, NEVER about yesterday.
