> “Everybody 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.” - Albert Einstein

I'm pretty sure Einstein never said this.

It's important to correct these misattributions, because they spread quite virulently and paint a saccharine picture of Einstein. He was a great scientist, let's understand him from his real work instead of from made-up poster quotes.

Here's the top Google result for this quote, which quite extensively examines it and concludes there is no connection to Einstein: http://quoteinvestigator.com/2013/04/06/fish-climb/

P.S. There's an easy heuristic to apply to Einstein quotes with a life lesson in them: he didn't say it. You'll be correct 95% of the time.
