I have a bunch of hobbies. I like being busy, and I like creating things. I always loved building toys as a kid, like Lincoln Logs and the Girder and Panel building set. Even when you know that what you are creating is essentially a sand castle — ephemeral, a cake to be eaten and not had — the lessons you learn from each effort make up who you are.
So in that sense, they are not ephemeral, these things that no longer exist in my particular space-time. The experience of creating them is now part of my “programming”. This website isn’t limited to those things which are deemed ephemeral. I just thought it was interesting to point out.
