"My God, does he ever shut up?" As average guys making the effort to kick up our everyday style a few notches, we want to make certain others never have this thought about us.
"It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt." -- Mark Twain
The advice offered above has also been attributed to various other public figures but has its origins in biblical verse. Regardless of who said it first, though, the words are very wise and well worth remembering in the continuous quest to improve our personal style. Talk is cheap as my father used to say, and unless you've really got something to say, it's far better to leave the endless stream of idle chitchat to others. Practice greater economy with your conversation. Sit back, observe, and let others do the talking.
