In The monk who sold his Ferrari we’re told that we think 60,000 thoughts a day, 95% repeated from the day before. In Finding your element, Chapter 1, Ken Robinson advises his readers ‘to turn down the [mental] noise’.
I figure that my tiredness is 60% due to stressing, 20% to physical condition, and only 10% due to aging. So it makes sense, if I want to feel better, to concentrate on improving my mental outlook.
In an Art book about Toulouse-Lautrec I read that Henri’s favorite expression was, “Ah, life!”
I think I’ll also adopt that as my own.
