There's a terrific feeling, when working through a project, of focusing on a single part of it and making just that bit completely good. The rest of the world can disappear, and things are calm and sensible. If only all of work could be like this, more often! Because there's many times when it feels impossible to focus enough, because there are 15 different things all needing to be thought about. I thank the gods of project management for issue-tracking systems.
