What things tend to slow a developer down?

Please try to refrain from posting answers that:


are slow now but useful in the feature. (TDD, Refactoring, ...)
list a distraction.


Oh this ones easy:


Meetings
More Meetings
Meetings about the last meeting
Meetings to prepare for the upcoming meeting
Developing a power point presentation for a meeting
Developing a power point presentation for a meeting discussing features that haven't been implemented, shouldn't be implemented, and for whatever reason that guy from sales will jump all over.  I can't predict what document you want displayed in the app based upon your current location without an internet connection or access to your hard-drive.  No really, just give up asking for it too.
