Just came here to write a followup in the current rationality diary post.

I'll see about it, I'm not sure yet... After all it would only amount to my two cents on the matter; I'm very aware of the fact that my observations and experiments lack scientific rigour (of the kind you can see for instance in gwern's articles on nootropics). I do however write down all the insights on productivity that I discover through my experience, and if and only if one day I produce the desired changes in my psychology and work-related behaviour, I'll coalesce them into a mini-sequence. Until then, though, I won't consider myself an authoritative voice on the matter.

For now I'll be posting updates in the rationality diaries, and see if anything more substantial comes out of it.
