You know, I felt really troubled to have been using something for 20 years and realize things had changed and it was no longer right and no longer good for me.

You know, I felt really troubled to have been using something for 20 years and realize things had changed and it was no longer right and no longer good for me. I felt like a fool for having stuck with it for quite so long. I realize that sounds like someone talking about a bad marriage, and I suppose we can generalize usefully on relationships of whatever type. I think we must end up with longer-lasting bad feelings about anything we used to value.
