It's a matter of ABC: When we encounter ADVERSITY, we react by thinking about it. Our thoughts rapidly congeal into BELIEFS. These beliefs may become so habitual we don't even realize we have them unless we stop to focus on them. And they don't just sit there idly; they have CONSEQUENCES. The beliefs are the direct cause of what we feel and what we do next. They can spell the difference between dejection and giving up, on the one hand, and well-being and constructive action on the other. The first step is to see the connection between adversity, belief, and consequence. The second step is to see how the ABCs operate every day in your own life.
