Control Obsessive AnxietyEntrepreneurs have to be very good at withstanding risk, which basically comes down to tolerating ambiguity. The profit picture can be very hazy for a long time, and entrepreneurs have to be able to hang in there with all the vagaries. Withstanding uncertainty requires an ability to regularly get the anxiety down. One of the best tools for this is the relaxation response, also known as meditation. It's a fantastic tool for calming the mind and eliminating obsessive thinking, and it's used in thousands of clinics, hospitals and homes throughout the country. All you have to do is sit quietly for 15 or 20 minutes and repeatedly think of a phrase in your mind, letting thoughts come and go as they will but always returning to the phrase. You'll be amazed at how this practice can cut down on anxiety. Pick up a copy of the classic on this technique, The Relaxation Response, written by Dr. Herbert Benson, for an easy introduction.
