In the same way, you cannot control that you…
In the same way, you cannot control that you are going to Los Angeles today. You can only intend to go to Los Angeles today and then take the prudence steps to get there. This could include buying a plane ticket, taking an Uber to the airport, getting on the plane, etc but in each one of these steps, something can come up and derail or the plane your expectations or your intent. Therefore you do not have exclusive control, although it may feel like you do.

In the book
And hold this humility about the decisions of others: when someone does a thing you find wrong, the honest response is not that they are evil but simply that you would not have done it — for in their own mind they very likely believed they were doing right. Remember, finally, that you can only ever intend an outcome and take the prudent steps toward it; you cannot command it, because between your action and your result stand a thousand things you do not control. [Here is the place for my own turbulence — write in, or let me tell you, about a decision I got wrong, how I made it, and what I changed afterward.] — Decisions & Choices (Decision/Choice/Focus/Forethought/Consequences)
