Key takeaways:

1. Our beliefs about being out of work, someone not talking to us, or being heavier explain how we feel — not the situations themselves.
2. Some examples of common beliefs:
   
   1. “I must not be very responsible because I’m out of work!”
   2. “I must not be very likable because doesn’t talk to me.”
   3. “I’m not as attractive because I’m heavier.”
3. If you think there is no way you can change your beliefs, your brain will agree with you and ensure that you can't.
