Interestingly enough, this sounds like the emotion that (finally) induced me to overcome akrasia and write a post on LW for the first time, which initiated what has thus far been my greatest period of development as a rationalist.

It's almost as if this feeling is to me what plain anger is to Harry Potter(-Evans-Verres): something which makes everything seem suddenly clearer.

It just goes to show how difficult the art of rationality is: the same technique that helps one person may hinder another.
