Teens and sleep

"By detachment I mean that you must not worry whether the desired result follows from your action or not, so long as your motive is pure, your means correct… a person who is worried about the outcome of his work does not see his goal, he sees only his opposition and the obstacles before him, feeling unequal to the difficulties of his situation, he becomes resigned or resorts to violence out of frustration and despair. But the man who is detached from results and tries only to do his best without thought of profit or power or prestige does not waver when difficulties come." -Eknath Easwaran
