I have started a list of concepts that I've found to be important to leaders, managers, and teams. It will serve as a comprehensive reminder when I am coaching people. The list will also be an important resource in daily business planning.
The list's subjects are described in very few words, often one or two. Nothing is lengthy but everything is important. The entire list is single-spaced.
I'm up to six pages and still going strong.
I recommend the technique, if only as a reminder.
