Nothing gets done unless I've written it down.
And so I make lists. Day to day lists of things I should get done, like take out the garbage or doing laundry or posting to my blog.
The adding of the item to the list frequently takes longer than the execution of the item would itself.
There's something comforting about a list, a sort of remedial map for the stupid, the ensuring that things aren't forgotten or mislaid (as so often they are), the perverse satisfaction of scratching items off when finally they're completed...
It helps me to recognize when things are done.
I've lists for outstanding art and literary projects, blog posts, finances, bills, menial day to day tasks, and even, in a recent stroke of genius, lists of lists.
A book, then spreadsheets, of things that need to get done. No one is more organized than myself.
