I kept a yearly journal in the late 90's because I wanted to see how much I spent on books and fabric. But they were really interesting with notes and business cards on various shops we visited, shows we attended, notes on current projects, and one year how much time it took to make every Dear Jane block. That one is on the Electric Quilt Dear Jane cd/dvd. One year how much time it took to hand quilt a whole cloth quilt (600+ hours).
It's purpose clarified things, and led to much wiser book purchases, and eventually in 2001 stop buying fabric.
Purpose accomplished, the desire to keep it up evaporated.
