Pressure is not stress. But the former is converted to the latter when you add one ingredient: rumination, the tendency to keep rethinking past or future events, while attaching negative emotion to those thoughts. Of course, leaders must practice reflection — planning for the future or reviewing past lessons — but this is an analytical, short-term process, with positive fallout.
Rumination is ongoing and destructive, diminishing your health, productivity, and well-being. Chronic worriers show increased incidence of coronary problems and suppressed immune functioning. Dwelling on the past or the future also takes us away from the present, rendering us unable to complete the work currently on our plates. If you ask ruminators how they are feeling, none will say “happy.” Most feel miserable.
Stress is not caused by other people or external events, but by your reactions to them.
In the workplace, many people blame their high anxiety levels on a boss, job, deadlines, or competing commitments for their time. But peers who face the same challenges do so without stress.
