Get away from your business once in a while! Everyone needs a break to relax and get re-energized. You will need to pre-plan your absence by finding the most capable and reliable employee, another business person or one of your family members to be trained and prepared as your backup when you are away.
You need to also train yourself to let go of control and learn the art of delegation. Provide your delegate with all the important procedures and information along with clear instructions and expectations. Have a trial run to test out the arrangement then fine tune the details so that your "get away" plan will be perfect when you need it.
