Philip YanceySomeone asked the Swiss physician & author Paul Tournier how he helped his patients get rid of their fears. He replied, 'I don't. Everything that's worthwhile in life is scary. Choosing a school, choosing a career, getting married, having kids--all those things are scary. If it is not fearful, it is not worthwhile.'
