It's a very interesting solution. I've been thinking more about filling my online time sheet system in advance but I suspect its too impractical to stick to times or keep readjusting with interruptions, so maybe I will try post-its.
I notice a bit of a link in behaviors between people I know who have ADHD and/or OCD. I'm not really sure what someone who "gives-in" to OCD impulses would feel as side effects, etc.. But I'm kind of curious if you see a downside to having followed loops for their reinforcing effects over days of work, etc?
