The real discovery is the one which enables me to stop doing philosophy when I want to. The one that gives philosophy peace, so that it is no longer tormented by questions which bring itself into question. Ludwig Wittgenstein
If you have only one passion in life - football - and you pursue it to the exclusion of everything else, it becomes very dangerous. When you stop doing this activity it is as though you are dying. The death of that activity is a death in itself. Eric Cantona
When you stop doing things for fun you might as well be dead. Ernest Hemingway
Since it could be done what was the use of doing it, and anyway you always have to stop doing something sometime. Gertrude Stein
Have I done something for the general interest? Well then I have had my reward. Let this always be present to thy mind, and never stop doing such good. Marcus Aurelius
I don't want to walk in the middle. I want people to read what I write and feel strongly about it. If, at some point, whatever I am doing is failing to elicit a response, whether it's very positive or very negative, then I am going to stop doing it. James Frey
