I found this quote on zenhabits.net. The link is at the bottom of the blog. It's quite an inspiring site. I recommend you go to the "Getting Started" link on the right side of Zenhabits if you decide to check it out. This is a huge site and it makes sense to start at the beginning.
The quote: "We are what we repeatedly do. Excellence then, is not an act, but a habit." ~Aristotle. So I figure this is going to be my response when DH or co-workers, friends call me "anal." I realize I am a bit uptight about some (many) things -- shiny sink, not leaving socks on the floor, making beds etc. Now I have a reason -- the quest for excellence is a habit that I am unwilling to break. So there.
