The monk who sold his Ferrari. Robin S. Sharma. Selected quotes XIV

-Sure I am that this day we are masters of our fate, that the task which has been set before us is not above our strengths; that its pangs and toils are not beyond my endurance. As long as we have faith in our own cause and and unconquerable will to win, victory will not be denied us. Winston Churchill
-The virtue of self-discipline is like a wire cable.
-When you continually practice the ancient art of self-government, there will be no hurdle too high for your to overcome, no challenge too tough for you to surmount and no crisis too hot for you to cool down. Self-discipline will provide you with the mental reserves required to persevere when life throws you one of its little curves.
-An abundance of willpower and discipline is one of the chief attributes of all those with strong characters and wonderful lives.
-Willpower allows you to do what you said you would do, when you said you would do it. It is willpower that allows you to get up at five in the morning to cultivate your mind through meditation, or to feed your spirit by a walk in the woods when a cozy bed beckons you on a cold winter's day. It is willpower that allows you to hold your tongue when a less-actualized person insults you or does something you disagree with. It is willpower that pushes your dreams forward when the odds appear to be insurmountable. It is willpower that offers you the inner power to keep your commitments to others, and, perhaps even more importantly, to yourself.
-It was one of the greatest,and saddest nights of my life.
-Through  the steel of discipline, you will forge a character rich with courage and peace. Through the virtue of will, you are destined to rise to life's highest ideal and live within a heavenly mansion filled with all that is good, joyful and vital. Without them, you are lost like a mariner without a compass, one who eventually sinks with his ship.
-Truly enlightened people never seek to be like others. Rather, they seek to be superior to their former selves. Don't race against others. Race against yourself.
-When you have self-control, you will have the resolve to do the things you have always wanted to do.
-Building self-control and discipline into your life will also bring you a tremendous sense of freedom. -Developing the power of your will can erase the worry habit, keep you healthy  and give you far more energy than you ever had.
-Self-control is really nothing more than mind control.
-Will is the king of mental powers. When you master your mind you master your life. Mental mastery starts with being able to control every thought that you think. When you have developed the ability to discard all weak thoughts and focus only on those that are positive and good, positive and good actions will follow.
