Spend a moment to consciously relax our hands, feet, and face. Deliberately unclench your hands and let them lie loose in your lap. Let your feet sit flat and unflexed on the floor. Relax your facial muscles.
Every time you write an email, take a full, deep breath before you start writing.
Take a mindful pause. Spend ten seconds focusing fully on your breathing, and then consider this question: what strengths and skills can I bring to the challenge in front of me?
