Words have power be it spoken or written. Words can motivate, decimate, heal, humiliate and humble. Once they are said they cannot be taken back, therefore, choose your words wisely. Think a hundred times before you utter a word and your relationships will never go sour.
As a writer I understand the power that words carry and how they influence our life. We humans use words to communicate with one another and it is the choice of our words that decides the effectiveness of communication.
Speak only if your words are more beautiful than your silence, it is what the wise say. Anyhow, the worst time to open your mouth is when you are angry. Everything that you utter in anger will only go against you because in anger one loses the ability to rationalize and when you lose the ability to distinguish between right and wrong you will most probably end up saying something that you might regret.
Raise your words not your voice. It is rain that grows flowers, not thunder.
Great writers are those who not only have great thoughts but who express these thoughts in words which appeal powerfully to our minds and emotions. Physical bruises heal in a week or so but the wound a word opens can fester forever.
