One who gains strength by overcoming obstacles possesses the only strength which can overcome adversity.
Albert SchweitzerLiving truth is that alone which has its origins in thinking. Just as a tree bears year after year the same fruit which is each year new, so must all permanently valuable ideas be continually born again in thought.
Albert SchweitzerAnyone 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 Schweitzer
