1.) Pay attention to yourself when you are under stress, and check for dissonant/involuntary responses.
2.) Decide what your new default response is going to be. Decide to ditch all the other responses.
3.) Practice the stress situation until the new response is fixed. Go back to #1.
In other words, decide what’s going to be your response to any given stimuli, and make it natural.
In other words, reframe everything and be nonreactive.
In other words, decide your own reality.
In other words, you are your actions. As long as your behavior is based on reaction, the matrix has you.
