I write everything down. I e-mail the second I think of something, or I write notes in my BlackBerry calendar. I set up reminder alerts on my phone. And I have a notebook by my bedside so I can write down any last-minute ideas. ↗
You know that I write slowly. This is chiefly because I am never satisfied until I have said as much as possible in a few words, and writing briefly takes far more time than writing at length. ↗
