Well, it's like everything, I have many toys because I have many interests. You can't do them every day, or they'd be work. So they get used while I'm engaged, then left til the next enthusiasm in their direction. Sometimes I lose the inspiration to do things in a specific line for years, but then suddenly the desire comes back again. It's been my life.
The nice part about enlarging my tool and skill sets is that when I go to do something adjacent that peaks my interest, I've already got the major part of the tools and skills, so I don't suffer that expensive hobby start or lengthy and disheartening learning curve. It also doesn't hurt so much to drop a hobby after a project or two, because I have the experience to know that although that particular thing didn't interest me, I understand that what I added to the tools and skills will be applicable to the next interesting thing.
