I have one suggestion for beginners:
Develop A Weekly Review Checklist and go through it with your weekly reviews. This gives you a check of last resort as you get started to make sure that you look at and clean all your buckets. As you play with your system and say, create a new folder to track your wizbangs, you should put a n item in your checklist to review wizbang folder.
This gives you a check of last resort and allows you to modify your system and still know that you will remember your changes because your weekly review checklist will remind you.
This gives me the freedom to make changes to my system and know that I can trust them.
