As part of my weekly review, I go over two (printed) pages of my "big picture" notes - life mantra, adjectives I aspire to, etc. Part of this is a bullet list of "self-defeating behaviors" that I suppose serves the same purpose as a not-to-do list.
I have a cool story about this: for awhile this particular habit was neglected as part of my Weekly Review - I technically looked at the page but I wasn't actually reading it. (Bad Marina!) A few weeks ago I sat down to really go over it, and I realized I had genuinely overcome those vices. Of course then I immediately thought of five new things to work on

Often for me, a "not-to-do" is actually a project, if I really think about it. Just writing something down won't stop me from doing it - I need different strategies to support me. For example, I had a bad habit of stopping for fast food instead of going to the grocery store, so I turned this habit around by taping a picture of a hot girl on my steering wheel (ha), keeping healthy snacks in the car, and adding "pack a lunch" to my nightly routine so I wouldn't get so hungry at the end of the workday.
