I am determined to develop a technique to avoid wasting time so I've been making a list of activities.
A couple of days were spent converting the list to sub-lists that are broken down by subject, frequency, and geographic location. Each of those in turn has a rating of A (Really Important), B (Important), C (Might Be Important), D (Don't Know), E (Looks Unimportant), F (Really is Unimportant) and G (Importance is Irrelevant). Each factor, of course, is weighted and the Two Standard Deviation formula is applied to avoid unfairness.
A week or so may be devoted to deciding if the sublists should be color-coded and whether footnotes are necessary. Clever acronyms will be assigned, but only after extensive research and debate. Care will be given to the system's three-ringed notebook, since appearance is always a subtle motivator.
Or perhaps it isn't. I'll check into that if I can find the time.
