Well, yeah, but maybe what I take from your perspective is that we should try new things on a regular basis. And--it doesn't take as much to maintain a skill as it does to gain it in the first place, you never forget how to ride a bicycle, but not doing it for a very long time will make you significantly worse at it, at least it does me. I'm right there with you with making things fun and interesting. Some weirdoes find running fun--one man's fun/slightly hormetic stressor is another man's hell.
