Stress is an indicator of our belief in the value and validity of our worries and fears.
As long as we define stress as how some person or situation is making us feel, we will have to change the world around us to find peace of mind.
You can't use stress, anxiety, frustration, and worry to deal with your stress, anxiety, frustration, and worry. It's like pulling up to a burning building with a flame thrower. The energy of the problem can't be the energy behind a successful solution.
Stress is a signal that something needs to change. Suffering, is when we don't make the change!
When stress and anxiety have your system stuck in a brainstem loop? Reboot. It's I.T. for life!
You can't 'cope with' change anymore than you can 'manage' stress.
