Use your word wisely.  This term as simple as it sounds has a very profound impact.  Depending on how you use words, they can lend themselves to creating harmony & peace.  If you use them to hurt someone they can have an effect that can last a lifetime.  Words can be more powerful than a weapon, which means that we have to give them more respect as we use them to communicate with those around us.  Learning to use your word wisely can sometimes mean that you do not respond immediately.  It may mean that you must think before you speak in order to avoid any unintended consequences.  These days we are not only communicating in person, over a phone, but now we use email and other forms of social media.  We live in a world with instantaneous communication channels. As easy as it seems to hit reply or send to a message, remember that your word (s) speaks volumes beyond the sentence that you just wrote.  Take the time to speak that which is true, only necessary and kind.  This formula will likely pay large dividends for you in the future.
