I was thinking about failure and success today after a chat with a friend and remembered a quote by Winston Churchill on the topic, i looked it up and found a few great ones by him:
"Success is the ability to go from one failure to another without the loss of enthusiasm"
"We make a living by what we get, we make a life by what we give"
"For myself i am an optimist- it does not seem to be much use being anything else"
tons of good quotes here
