Poll: What is your #1 productivity killer?
For me it comes from decision paralysis.  "I should finally go through a Haskell tutorial!  Well wait, there's still so much I should learn about python.  I should build something with it.  Maybe a simple web site, I already have familiarity with that.  I could use one of those frameworks, Django, Flask, Bottle, Pyramid...that reminds me, I never got through my ASP.net book, I spent $30 bucks on that, should at least finish it.  Ah but I'm right in the middle of Slaughterhouse Five, and thats been really good--Fuck it, whats on reddit."
