I have gone literally months walking past the layout with no intention of doing a single thing. Not even powering it up for five minutes. Then, when the verve returns, I get at it. Almost always there is something else competing for me time and me talents.
I garden seasonally. I'm not a pro, nothing like a 'master gardener', but I know what I like and I'm busy at it for four solid months each year. Now I have a nice shiny refractor telescope and go-to computerized mount and tripod sitting in the dining room gathering dust. I also have a concerning heart condition. These things all cost in some way. They take energy, focus, learning, note-taking, getting replacement items that bring pleasure or utility to what you're doing...
One must husband one's resources. Time and interest are resources.
My dear old Dad told me, when I was a young boy, to keep things special. Anything done too often, too much, will lose its power. You'll think you need, and you will want, more of it. This could be on-line vices (you know what I'm talking about), drugs, and other pursuits that eventually take over our lives, or that we ruin or reduce by making them routine or mundane. He was talking about things like chocolate bars, chips, soda pop, or other pleasures. This was 55 years ago, but even in modern times the same processes apply.
Move on to something else when there's simply no mood or desire. After a few weeks, I often find that something I have ignored or neglected, or overdone, takes up its strength again, and the pleasure intensifies.
