“If I were to name the three most precious resources of life, I should say books, friends, and nature....”
“The most precious things I have in my life were not bought, they were earned.”
“Think of the inconvenience of vanishing as it were from your friends and, correspondents three times in one's natural life.”
“There are three things that grow more precious with age; old wood to burn, old books to read, and old friends to enjoy.”
“My favorite things in life don't cast any money.It's really clear that the most precious resource we all have is time.”
“If, then, I were asked for the most important advice I could give, that which I considered to be the most useful to the men of our century, I should simply say: in the name of God, stop a moment, cease your work, look around you.”
