A quick update before we begin- I’m in the final stages of editing The Stoic Manual: Meditations on the Art of Living, a collection of 150 Stoic meditations on living well. It’ll be released soon and included free for all Annual and Lifetime members.

Tissue begins to look like mere material- something to grasp, move, expose, divide, and repair. Experience teaches you to remember that it’s living. It bruises. It tears. It may never even recover from what your hands do carelessly.

There were two other lessons repeated until they became instinctual. You must expose enough to see what you’re doing. And before you divide anything, you must know exactly what it is. Many disasters in theatre begin with a surgeon acting decisively on a mistaken idea of what lies beneath the surface.

The longer I’ve lived with other people, the more these rules have become useful outside the operating theatre. A good relationship asks for much the same discipline- where we show…
