If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
[Meta] I often see threads like this where people recommend things that require a very high level of conscientiousness or planning ability to start with, (e.g. if you are tired in the mornings get out of bed immediately and do x, requirs you to be capable of forcing yourself to do x when you are tired.)
I think you are mistaken about what is easy and difficult. Most of these are about dealing with lack of willpower, suggesting that the authors found something that was easier than it looked. Most of them don't compare before and after, but jsteinhardt's does.
