I’m a big fan of GTD’s Ubiquitous Capture – dump everything in your head on paper (or in some kind of text doc or voice note), thus allowing yourself to focus on important stuff – no need to worry about remembering the little bits and bobs, more brain power available for deep thunkful thoughts. You can then later review your ideas and act upon them when in a space more suited to processing. The problem comes though when you forget to record something at the moment of creation. With no habit of recalling recent thoughts to record or act upon it slips through the net.. And you end up in situations like I’m in now – running 20 mins late for a meeting that I’d completely forgotten about having not added it to iCal. I guess total dependence is never a good thing.
