There's a Zen concept of "non-attachment" that I like to apply to everyday life, when I'm not too stressed out to remember it. At its core is a pretty simple concept: let go of your attachment to things, because things are short-lived, and desire for things can make you miserable.

It used to be that we'd joke about ease of use by saying "even my grandmother can figure it out." But the cold facts are that there's a better than zero chance that someday we'll be grandma's age and have to deal with user interfaces designed by bratty ingrates with no respect for the Old Ways.

It seems to me that one way to avoid (or at least delay) becoming a cranky "old person" is to accept that things will change, will always change, and not become too married to our favorite apps, interfaces and ways of doing things.
