All important progress made by the human race has its roots in daydreaming.

Although there are real hazards in saying yes to life, they are inconsequential when compared to the regrets that come with saying "no".

Excellence in life seems to me to be the way in which each human being makes the most of the adventure of living and becomes most truly and deeply himself, fulfilling his own nature in the context of a good life with other people.
