Don't spend too much time on a main note

You do not need to develop a main note to maximum sophistication. Spend more time on the relationship to other notes. (The value of an idea is determined by its relationship to others)

[Luhmann's] main concern was not to develop an idea to maximum sophistication; rather, he operated on the assumption that a decision on the usefulness of a note could only be made in relating it to the other notes.

I can spend anywhere from one to ten minutes on each note. Spending longer seems to defeat the purpose of allowing the value of ideas to be defined by their relationship to one another.
