I was an unusual young man then, around eighteen years old - precocious in a hundred ways but very far behind and helpless in a hundred other ways. When I compared myself to other people my age, as I would do every now and then, I sometimes felt proud and conceited but just as often demoralized and depressed. There were many times I saw myself as a genius, many times as half insane. I was never able to share and join in the others' pleasures, and I was eaten up with worries and self-hatred about how hopelessly isolated I was from them, how cut off from life.
