"Experiences are savings which a miser puts aside. Wisdom is an inheritance which a wastrel cannot exhaust" - Karl Kraus

"Good judgment comes from experience and experience comes from bad judgment" - Fred Brooks

"Nothing is a waste of time if you use the experience wisely" - Auguste Rodin

"The only source of knowledge is experience" - Albert Einstein

Innocence is being a child, Experience is that child growing up, like Blake tells in Songs of Innocence and Experience.
