Think before you speak. Read before you think. This will give you something to think about that you didn’t make up yourself – a wise move at any age, but most especially at seventeen, when you are in the greatest danger of coming to annoying conclusions.
– Fran Lebowitz, The Fran Lebowitz Reader
This particular quote is from the Tips for Teens chapter, originally published in the stand-alone Social Studies volume. (Some of these witticisms are absolutely hilarious; I caught myself laughing aloud.)
