It’s doesn’t matter how well you chunk up your time, if it’s all the same kind of work, you’re on a slow slide to inefficiency.

By bandwidth I mean basic cognitive resources — psychologists call them working memory and executive control — that we use in nearly every activity. Bandwidth is what allows us to reason, to focus, to learn new ideas, to make creative leaps and to resist our immediate impulses. We use bandwidth to be a good participant at an important meeting, to be a good boss to an employee who frustrates us and to be attentive parent or spouse.

I’m pretty pleased with what I’ve got – but that’s the end of the really demanding cognitive work I can do today.
