I first heard the term Day Book years ago when I was temping for some senior training guru at Xerox. The day book/file was for any papers related to that day. Simple really but pretty effective in focusing attention on that one particular days demands and needs.
On Flickr I saw this http://www.flickr.com/photos/martintaylor/ gr8 version of a day book, things that are noticed by the photographer daily.
So this year I am going to do the same, with a bit of a hiccup in week one I'll admit, but from today I'll post daily images here http://www.flickr.com/photos/42165066@N03/
Do post if you have something similar going on
