Never stop fighting until you arrive at your destined place - that is, the unique you. Have an aim in life, continuously acquire knowledge, work hard, and have perseverance to realise the great life.
There is no harm in patience, and no profit in lamentation. Death is easier to bear (than) that which precedes it, and more severe than that which comes after it. Remember the death of the Apostle of God, and your sorrow will be lessened.
