Ou know, something that changed the way you looked at things.What's a life changing statement from a book?Interesting! There are so many books to choose from!
The Bible is the first thought, but I think You're looking for something more secular!
My favorites are the poem %26quot;Desiderata%26quot; and anything from the book by Kahlil Gibran %26quot;The Prophet%26quot;!
%26quot;Go placidly amid the noise and the haste, and remember what peace there may be in silence%26quot;!
