I posted on another thread about my filing project. My Action of working on one file a day sometimes worked and other times didn't. Then this week something kicked in, time allowed and I just started taking bundles of files and working them. In a two day period I spent hours going through and working it.
So, maybe by having your, work 20 bookmarks, you will do 40 one day, or a hundred. The important thing is to keep it in front of you.
