This is an interesting post on why perfectionism is usually counter-productive (though it is not put in these terms).
A quote of a quote from the website: "... simplicity ... is best described as the state of grace arrived at by a sober, modest, heartfelt intelligence. The main strategy of this intelligence is economy of means. Pare down to the essence, but don’t remove the poetry. Keep things clean and unencumbered, but don’t sterilize. .... Usually this implies a limited palette of materials. It also means keeping conspicuous features to a minimum. But it doesn’t mean removing the invisible connective tissue that somehow binds the elements into a meaningful whole."
I took out the "wabi-sabi" stuff ... for the passages expresses the spirit of craftsmanship present in all cultures.
This approach obviously has some relation to minimalism in computing and note-taking.
