• Established a useful new habit

Taking zinc on the first signs of a cold. Seems to have avoided three cases but whether it shortens a cold remains to be seen.

• Obtained new evidence that made you change your mind about some belief

• Decided to behave in a different way in some set of situations

I read "Getting to Yes" and used that to improve negotiations (one with a mechanic). The change mostly consists in asking questions instead of making my own position transparent (transparency is good, but position is not).

• Optimized some part of a common routine or cached behavior

I made a habit to consciously reflect on the future merit of web-pages I'm browsing instead of just following my intuition (and impulse). It led to skipping quite a few low to medium value pages.

• Learned something new about your beliefs, behavior, or life that surprised you

My model of my own learning was that I adapt quickly to new information - but often overshoot the target. I believed that I this was a sign of quickness of mind but when thinking about the differences in reasoning and how fast we adapt to new information I realized that my overadapting really might mean that I take facts too literally. That I don't sufficiently question the underlying assumptions - and thus overshoot. I'm still not clear how to deal with that. The good thing is that after overshooting I return equally fast - if given further input/feedback.
