"Time as an Art of Living" - this is a successful book and the major theme of Olaf Georg Klein. Now, Klein turns to diary writing: Who does it, at what age and in what form, and how does one get started? Is it better to write with a pen or on a computer, spontaneously or thoughtfully, daily or only occasionally, while traveling or in everyday life, in short notes or long sentences? Is it permissible to correct diary entries? Are they still authentic then? And in general: Who should read them? How did the famous diarists in history handle their records? Olaf Georg Klein knows that diary writing gives more time than it consumes - and that writing multiplies life. He demonstrates how to use a diary to sharpen memory, think more concretely, feel more intensely, and live more fully.
