BBC - Capital - Is it Zen, or just the art of getting things done?
GTD boils down to something like this:
"1) Adopt a reliable capture method (Evernote, voice memos, a Moleskin notebook, etc) to get thoughts out of your head.
2) Distill them to actionable items and next steps (“send receipts to Finance”, “call a kick-off meeting for an office-wide re-org”) on your daily to-do list.
3) Dedicate yourself to multiple reviews in which you put these action items into the right buckets (“must be done today”, “phone calls when I’m on the train”).
4) Do the things on the list, when you have time, prioritising as you go."
