It’s so important to develop mastery over the whole life sequence: think nice thoughts, speak kind words, do good deeds, and develop positive habits. This is one of the secrets to life itself.
Life is often in the hands of our tongue–one stupid word and it can mean your head, and one smart thing and it can be, with G-d’s help, your ride to the stars!
Indeed, controlling your words, like controlling your desires, temper, and so on is a constant challenge we all face throughout life. Yes, it’s easy to just let oneself go, but the consequences can be severe for shooting off your mouth, acting stupid, or getting angry. We can get better with patience, time, and practice. We can become better, stronger people. We can learn to guard not only our tongue, but our temperament and deeds, and live a better, and perhaps even a longer life for it. 😉
