I use:
“In-box” for anything that comes to mind, new commitments etc;
Diary;
Context/Agenda lists: @on the road, @hardware store, @home computer, @wife (re: holidays, schools, finances etc), @parents, etc;
Personal Projects list;
Outline project planning – bullet points on a single page covering the main steps of a project, including desired outcome;
Someday/maybe list (depressingly long);
Reference, which includes birthdays, books I might buy (which could also be called @bookshop), CD’s I might get etc;
Phone numbers.
