" I was not born happy. As a child, my favourite hymn was :'Weary of earth and laden with my sin.' At the age of five, I reflected that, if I should live to be seventy, I had only endured, so far, a fourteenth part of my whole life, and I felt the long-spread-out boredom ahead of me to be almost unedurable. In adolescense, I hated life and was continually on the verge of suicide, from which, however, I was restrained by the desire to know more mathematics. "

― Bertrand Russell , The Conquest of Happiness
