To understand mental strength, you have to learn how your thoughts, behaviors, and feelings are all intertwined, often working together to create a dangerous downward spiral as in the preceding example. This is why developing mental strength requires a three-pronged approach: 1. Thoughts—Identifying irrational thoughts and replacing them with more realistic thoughts. 2. Behaviors—Behaving in a positive manner despite the circumstances. 3. Emotions—Controlling your emotions so your emotions don’t control you.
