I realized that journaling at the daily level is absurd, things change too often and that’s what Twitter is for (and why I post tweets to my site first). But the weekly level seems granular enough to look at big and small events alike, but more removed from the small hiccups that could feel big for that day or moment.
I think there are many people who struggle with a daily journaling practice like Ben has. I think the most helpful thing to remember is that there are no “rules” except the ones you decide to set for yourself and even then nothing is set in stone. If a weekly or monthly practice work better for you, go for it.
