Tim Harford writes about productivity:

There are so many things one could be doing at any particular moment, and so many variables — where you are, how much energy you have, whether you’re being interrupted — that the whole exercise can feel like a game of five-dimensional chess that frequently leaves even the most skilled and seasoned players bewildered by an unexpected move.

This was such a great description that I had to share it. His advice, drawn heavily from GTD, is:

1. Look ahead (i.e. do weekly reviews)
2. Clarify
3. Be content (Oliver Burkmean style)

💯, as the kids would say.
