My purpose in sharing what follows is to help others that might benefit from it.
I'm glad I did the heavy work building my medium-sized around the walls layout (35 feet long and 4 feet wide) in my mid 40s long before retirement, which still has not happened at age 68. I do not have the motivation or energy that I had in my 40s, when I had young children who were excited about helping their dad with the layout.
I still enjoy doing smaller projects on the layout that keep the creative juices flowing, but take much less time and energy than building the whole layout. For instance, this past few months I used parts of a kitbashed engine house to create a front wall to my Yankee Stadium, I scratch built my Polo Grounds, and hung a backdrop behind the Polo Grounds.
We are all different, but I suspect that my experience is not uncommon. Arnold
