Anyone who proposes to do good must not expect people to roll stones out of his way, but must accept his lot calmly if they even roll a few more on it. A strength which becomes clearer and stronger through experiences of such obstacles is the only strength that can conquer them. Resistance is only a waste of strength.
Albert SchweitzerTo educate yourself for the feeling of gratitude means to take nothing for granted, but to always seek out and value the kindness that stands behind the action. Nothing that is done for you is a matter of course. Everything originates in a will for the good, which is directed at you. Train yourself never to put off the word or action for the expression of gratitude.
Albert Schweitzer
