Nausea (1938)

When I was in high school, reading everything I could get my hands on, spouting all kinds of weird shit at the dinner table, my mother, in an effort to encourage me further, gave me books of quotations, one of which included this great Sartre quote. It was only later, while bumming around Europe after graduation, that I came upon the context for Sartre's quote in his novel Nausea (1938).

Here it is in English:

Three o'clock is always too late or too early for anything you want to do.
