Fran LebowitzSmoking is, as far as I am concerned, the entire point of being an adult. Many people find smoking objectionable. I myself find many - even more - things objectionable.

Fran LebowitzI have a hard time writing. Most writers have a hard time writing. I have a harder time than most because I'm lazier than most. [...] The other problem I have is fear of writing.

All the time I'm not writing I feel like a criminal. [...] It's horrible to feel felonious every second of the day. Especially when it goes on for years. It's much more relaxing actually to work.
