Do things with your whole heart, with as much intensity as you are capable of. Anything done halfheartedly never brings joy to life. It only brings misery, anxiety, torture, and tension, because whenever you do anything halfheartedly you are dividing yourself into two parts, and that is one of the greatest calamities that has happened to human beings - they are all split.
