There really is no right or wrong way to do weeknotes and I change up my format regularly as otherwise I find they get stale and I lose interest in writing.
As for whether they’re interesting to read — yes, definitely! I read far more than I ever write, and I adore hearing about people’s weeks. Whether they’re long or short, vague or specific, reflective or factual; I always find a nugget of something thought-provoking in every set of weeknotes.
