Dale Pike at Stand Up Eight has created a sign for reminding himself on Getting Things Done methodology – Process, Organize, Review, Do. It is in PDF and you can download it, print it, slip it to different stages to remind yourself what you should focus on.
Update: Dale has contacted me – he is currently migrating his site to a new domain but unforuntately there are some database corruptions, and that’s why the site is unreachable now. He asked me if I can kindly host the GTD desktop signal PDF here. Dale, sure, here is the PDF. I will remove the link to your site until it is fixed.
Update: Dale has fixed his site – changing back the link to his site.
