I've grown to realize the joy that comes from little victories is preferable to the fun that comes from ease and the pursuit of pleasure.
Nothing can be so amusingly arrogant as a young man who has just discovered an old idea and thinks it is his own.
Anger at lies lasts forever. Anger at truth can't last.
Anger is never without Reason, but seldom with a good One.
The supreme irony of life is that hardly anyone gets out of it alive.
The happiest is the person who suffers the least pain; the most miserable who enjoys the least pleasure.
The gem cannot be polished without friction, nor man perfected without trials.
