Communication as a way of expression, is a time-based action.
To realize the value of 1 hour, ask a person who just lost the train.
To realize the value of 1 month, ask a mother who just gave a birth to premature baby.
To realize the value of 1 year, ask a student who failed a grade.
To realize the value of communication, ask the person who listened to his friend talking shit.
Be careful what you talk and what you do. It will cost you more than what you think.
