It's your life-but only if you make it so.

Each time you learn something new you must readjust the whole framework of your knowledge

Probably the happiest period in life most frequently is in middle age, when the eager passions of youth are cooled, and the infirmities of age not yet begun; as we see that the shadows, which are at morning and evening so large, almost entirely disappear at midday.

No one is all-knowing and therefore all of us need both love and charity.

We are given in our newspapers and on TV and radio exactly what we, the public, insist on having, and this very frequently is mediocre information and mediocre entertainment.

I believe that all that we go through here must have some value.
