One of the tell-tale signs of stress is grandiosity. We believe that we and only we can do each and every aspect of the job. So we take everything onto our own shaking shoulders - which just increases stress levels.
START TO DELEGATE before necessary. The best time to coach others is when we are relaxed. Once in panic mode we are less patient and efficient in giving instructions.
EXPRESS FAITH in your chosen delegate, even if you have reservations. Positive expectations encourage positive results.
VIEW DELEGATION as a training task - this will maintain you in coaching mode rather than supervisory or nagging mode.
MONITOR your delegation habits - regularly check your workload for tasks you could be delegating.
