Measure Your Words
I always recommend speaking with measured words—not going to the extremes of either complete silence or constant talking. Speak only when there is a need, and even then measure your words. Talking takes a lot of energy; and unnecessary speaking creates a lot of problems. You often make enemies by talking too much.
Occasionally observing silence for a time is a great practice. Silence is golden. Silence saves. I would recommend that practice to everyone.
