Two rules we should always have ready,—that there is nothing good or evil save in the will; and that we are not to lead events, but to follow them.

Two claims, and both are demanding. The first says the only place things go genuinely well or badly is in what you choose, which takes the weight off outcomes and puts it on conduct. The second says events are not yours to steer, and the sane posture is to meet them as they come rather than insist in advance on their shape. Between them you are responsible for one thing and relieved of the rest.

When a plan gets overturned, notice how much of your distress is about the event and how much about having been overruled. Then decide what a decent response looks like from where you now are.
