Men spend their lives in the service of their passions, instead of employing their passions in the service of their lives.

Notice who is working for whom. An appetite in its right place makes a life better: the drive that gets hard things finished, the affection that keeps a household together, the taste for a subject that lasts thirty years. The same energy left in charge organises everything else around itself, and the life ends up being run for the sake of the feeling rather than the other way round.

Take the strongest pull in your life and ask what it has cost lately. If it has been taking rather than giving, keep the appetite and put a fence around it, so it serves the week instead of setting it.
