1. When you find yourself caught up in your thoughts, switch your attention away. Stare out at the sky, focus on your breath, or talk with a friend. Every time you disrupt your inner monologue, you weaken it.
2. Prioritize activities you find naturally interesting. What activities easily capture your attention? The more you stay in an attentive, focused, CEN state, the stronger those networks become.
3. If you have a consistent, negative thought or belief, pressure-test it. Look for examples that prove the belief wrong. You may need to do this exercise with a trusted friend or therapist, who may see things more objectively than you can. For example, if you beat yourself up for having a messy house, a friend may come in and say, "Yes, but look at all the things you are doing. You are doing great at work, taking care of the kids, checking on your parents, etc. The one thing to fall by the wayside is the cleanliness of your home. That is good prioritization—not an inherent fault in you." Whereas the DMN makes every last thing the end-all-and-be-all, this exercise can contextualize the thought and loosen its strength.

To protect your mental health, exercise your mental flexibility. As you make your thoughts and attention more flexible, it can protect you from depression, anxiety, and believing things that just aren't true."
