Write a short story every week. It's not possible to write 52 bad short stories in a row.

War’s never a winning thing, Charlie. You just lose all the time, and the one who loses last asks for terms. All I remember is a lot of losing and sadness and nothing good but the end of it. The end of it, Charles, that was a winning all to itself, having nothing to do with guns. But I don’t suppose that’s the kind of victory you boys mean for me to talk on.

Really knowing is good. Not knowing, or refusing to know, is bad, or amoral, at least. You can't act if you don't know. Acting without knowing takes you right off the cliff.
