Pessimism destroys, naive optimism wastes life energy. Confidence, on the other hand, is the inner freedom that gives us the strength to surpass ourselves, even when circumstances are adverse, because we attribute meaning and joy to our actions. Confidence is the source from which body and mind draw energy when times are tough. The latest findings from medicine, neurobiology, psychology, and philosophy show that it is not the challenges that are decisive, but the inner attitude we adopt towards them. Bestselling author Ulrich Schnabel entertainingly and thoroughly explains the current research results from various disciplines in his latest book and demonstrates how we can rediscover and develop the ability to be confident within ourselves.
