Every leader faces a share of irritating screw-ups and minor setbacks. In response to those annoyances, some leaders get irritable and stressed out. Others keep on moving. To be in that enviable latter category, you need resilience. Train your brain to bounce back from hassles rather than get snagged by them. Find a quiet place where you won't be interrupted. Sit comfortably and focus on your breath. Notice yourself inhale and exhale. Don't try to change your breathing, just be attentive to it. As thoughts, sounds, or other distractions come up, let them go and return your attention to your breath. By doing this 30 minutes a day you will teach your brain to go to a quiet calm place when it is stressed, rather than triggering your fight or flight response.
