“Never miss the opportunity to keep your mouth closed.”
“Never miss a chance...to keep your mouth shut.”
“Life is fraught with opportunities to keep your mouth shut.”
“Never miss an opportunity to show your love, especially to those close to you, because we are always at our most cautious with them for fear of being hurt.”
“Never miss an opportunity to be fabulous.”
“It is better to keep your mouth closed and appear a fool than to open it and remove all doubt.”
