Since 2004, I've helped people take charge of their lives by getting the clutter and chaos out of their lives. It's important to find out first what works for you and learn as much as possible about your personal style.  It's worthless to create a system for you based on another person's accomplishment, then find out the system was not manageable for you.  With my experience in organizing technical projects and accounts, I've come to learn that my customers are all different and each is an individual with their own needs and ways of doing things.
