Habits are like submarines; they run silent and deep.
Life is not accountable to us. We are accountable to life.
You must welcome change as the rule but not as your ruler.
Time And health are two precious assets that we don't recognize and appreciate until they have been depleted.
Unless what you say benefits the other person, don't say it.
Focus all your attention and energy on the achievement of the objectives you are involved with right now.
