I find a lot of value in lists, sticky notes, and scribbles on paper, in order to keep my headspace as free as possible from having to remember things that can instead be written down and recalled. David Allen, a productivity guru whose work I came across many years ago, has had a profound impact on my life, not least of which because of his aspirational state of mind, called Mind Like Water. As the common definition goes, it is a mental and emotional state in which your head is clear and able to create and respond freely, unencumbered with distractions and split focus. Done correctly, it allows one to become more receptive to finding a natural flow, where tasks unfold and get knocked off the list in a logical and organic sequence. The incredible mental peace I find when DJing and long distance running seems most serene when I have dumped everything I possibly can out of my head and into a bucket to deal with at the contextually appropriate future time and place.
The challenge, of course, is being diligent with it all, not just in dumping things out of your head whenever you can, but also in remembering to check your lists and notes regularly once you have made them. My assumption is that children would hardly be afraid of a Santa Claus that made detailed notes of their behaviour, but never bothered to return to those notes before coming to town. As with many things, keeping the discipline is easier said than done.
