I think that is a good observation. I'm not sure I know anyone who would like any of these things in situations where they "had" to do them, and make them work on a tight deadline. Changing a flat tire to have a functional bike for your commute the next day is the opposite of zen for most of us.

So you do it when you have the time to do it. Which of course involves making time for it. I tend to involve my children in most of these things. Like my five year old helped me spartle the walls in her new room. Similarly if I'm working on my cargo bike I'll get theirs out and let them work on their bikes beside me if they ask to join. A lot of the time... like with the spartling I'll have to "fix" it later, but what letting them join does, aside from being a join activity, is that it gives me time to actually do these things on a busy schedule.
