He was in many ways an obsessive man
he was obsessed with cleanliness, he synchronised the clocks in his apartment; he regularly sent cards to himself to test how well the postal service was working.

"The fact that he was more vulnerable and receptive than other people was no doubt an important feature of his genius"
In his lighter moods, sport was one of his main recreations, although he preferred spectating or umpiring to participating (he was a qualified football referee. He also enjoyed playing card games, particularly Patience. Both light and dark sides of his character were evident in his fondness for satirical writers such as Gogol, Chekhov and Mikhail Zoshchenko.

"he tried to help so many people that
less and less attention was paid to his pleas."
