I feel I could write a long response to every comment in this thread as notekeeping is something I consider critical. Knowing when to commit to “The capital-N Notebook” is something I’ve struggled with as well. What has been effective for me is to scribble daily on a marker/chalk/dry erase board and then transpose the final thought into “The Notebook” at the end of each day. This lets me format, err, mull, etc. and the final (sic clean) notebook still has enough granularity to retrace my thoughts in the med-to-long term.
