I do understand and believe those thoughts offered in the answer, but they don’t really follow on from the thought “I am in control of whether I get this job” in a way that helps me to keep believing that I had that control even when I later found out I didn’t get the job.

“I am learning the difference between circumstances out of my control and results I control through mindful thinking” – yes! I am!
Can you help me to understand where that difference is, where the line is drawn?
In the example of the job, I thought that the decision the board of directors would make about whom to hire would be categorised as a circumstance out of one’s control. But when Brooke said, “You are in control of whether you get the job or not. If you believe the decision is THEIRS whether you get the job or not, you’re doing it wrong.” then I understood her to mean that it’s a result that one can control through mindful thinking.
Can you help me to understand what Brooke means here, given that it’s a fact that THEY (board of directors) make the final decision, and that other people’s actions are not in our control? What does she mean when she says it’s not THEIR decision?
