Other quotes to have as tattoos include "never a failure, always a lesson," which indicates that mistakes in life should be seen as learning opportunities. A quote from a famous poem includes "...and miles to go before I sleep," which comes from Robert Frost's poem "Stopping By Woods On a Snowy Evening."
