"The knowledge that you have emerged wiser and stronger from setbacks means that you are, ever after, secure in your ability to survive. You will never truly know yourself, or the strength of your relationships, until both have been tested by adversity. Such knowledge is a true gift, for all that it is painfully won, and it has been worth more to me than any qualification I ever earned." - J.K. Rowling
This is from J. K. Rowling's commencement speech to Harvard 2008 graduates. I enjoyed the read.
