I like to keep a tally of arts I've made in makeshift daily calendars like the one above (and a separate "monthly highlight" calendar) regardless of my progression of arts. Each day showcases the favorite art of that day (if multiple were made), and even includes bad scribbles and vent art.
I like to look back on them as sort of time capsules not only of what I've made, but also seeing my output but also as lil journals to remember what was going on at those times.
