"In life, pain is inevitable, suffering is optional. Sean Stephenson - in "Get Off Your "But"
"It is impossible to live without failing at something, unless you live so cautiously that might as well not have lived at all- in which case, you fail by default." J.K. Rowling's commencement speech at Harvard.
What can I add to those, sometimes life is hard. Such is life. I pick myself up, dust myself off, and move on.
