" This becoming more aware of what is happening now, and attempting to respond only to what is happening now, has almost magical results in relieving the “jitters.” The next time you feel yourself tensing up, becoming jittery and nervous—pull yourself up short and say, “What is there here and now that I should respond to? That I can do something about? "
