Albert Einstein's famous quote:
1) Every one is a genius, but if you judge a fish by its ability to climb a tree it will live its whole life believing that it is stupid. All people are geniuses, but if you judge a fish's talent by judging how well it climbs a tree, it will always be a fool.
2) We cannot solve our problems with the same thinking we used when we created them.
3) Insanity: doing the same thing again and again and expecting different results Definition of mental illness : A person who repeats one thing over and over again and expects different results
