The key to transforming your relationship to stress is to stop letting it overwhelm you. More and more people are discovering that mind-body practices such as yoga and meditation can be hugely helpful in shifting the way they react to stress.
So how do you shift your perceptions so you no longer feel like one big rubber band about to snap? That's where yoga and other mind-body approaches come in. Yoga teaches you to tune in to what your body is telling you and to act accordingly.
With practice, this awareness will spread into other areas of your life, including your work. As you learn to separate the urge to act from the reaction, you begin to find that something like a canceled meeting or having a last-minute project handed to you may not rattle you as much as it once did. You can detect stressors—what Buddhists call the spark before the flame—earlier, then pause long enough to think, "Well, maybe I don't need to respond."
