I'm trying to write more! I forget where I originally read it, but I think Ben Horowitz said something to the effect of "Clear thinking is best expressed in writing, so you can refer back to it later and see if your logic was correct." Been blowing up Confluence at work like a fuckin' fiend, and been blogging a lot more on my personal site.

I don't have any objective measures for this, but I think it's helped me a lot - it gets my head straight about the "why" of actions I've taken. That's valuable, if not terribly measureable!
