Life is simply time given to man to learn how to live. Mistakes are always part of learning. The real dignity of life consists in cultivating a fine attitude towards our own mistakes and those of others. It is the fine tolerance of a fine soul. Man becomes great, not through never making mistakes, but by profiting by those he does make; by being satisfied with a single rendition of a mistake, not encoring it into a continuous performance; by getting from it the honey of new, regenerating inspiration with no irritating sting of morbid regret; by building better to-day because of his poor yesterday; and by rising with renewed strength, finer purpose and freshened courage every time he falls.
