Focus, planning & productivity

Most productivity advice assumes every day is the same and every person is the same. These pieces take apart the standard rules — eat the frog, morning deep work, quarterly goal setting — and look at when they hold, when they don't, and how to adapt them to make them more useful for you every day.
