Do you think about what you say?
Are the words that come out of you mouth wasted upon deaf ears? Have the words you have said made those ears deaf to you?
You give your words power, but only the listener gives them value. If your words are always destructive, negative, and violent, people will begin to ignore them.
Let your words be a comfort, let your words hold real power, let your words inspire. I work with a young lady who inspires me regularly. Not be profound words, she often talks of daily life, school, and sillyness. Yet, her constant joie de vive reminds me how life shouldn't be taken so seriously.
As I let go of the serious path, I find my mind filled with deep thoughts. The musings of a sage and of a child are not so different.
