Illusions: The Adventures of a Reluctant Messiah
This book by Richard Bach is filled with inspirational quotes and the entire book is amazing. Here are just a few.
"If your happiness depends on what somebody else does, I guess you do have a problem."
"In order to live free and happy, you must sacrifice boredom. It is not always an easy sacrifice."
"The mark of your ignorance is the depth of your belief in injustice and tragedy. What the caterpillar calls the end of the world,the master calls a butterfly"
"The bond that links your true family is not one of blood, but of respect and joy in each other's life. Rarely do members of one family grow up uner the same roof."
"Your conscience is the measure of the honesty of your selfishness. Listen to it carefully."
and my personal favorite, but youmight need to read the book to apreciate it:
"Everything in this book may be wrong."
