"In the middle of every difficulty lies opportunity." - Albert Einstein
"The pessimist sees difficulty in every opportunity. The optimist sees the opportunity in every difficulty" - Winston Churchill
"I have not failed 700 times. I have not failed once. I have succeeded in proving that those 700 ways will not work. When I have eliminated the ways that will not work, I will find the way that will work." - Thomas Edison
