A wise person knows that there will be times that adhering to silence is the smartest thing to do. There is a saying that says it is better to shut your mouth and be thought a fool, than to open your mouth and remove all doubt.
A fool actually believes they themselves are wise. Unfortunately they are not willing to listen to wise council because they think they are the wise council.
How do we make sure we are not included in the category of fools? Ask yourself, do you have all the answers or do you have all the questions. A wise man knows the right questions and is always looking for more answers.
