If you ask a search engine for quotes about mistakes, you get hundreds of results. Every celebrity and wannabe celebrity seems to have said something bright or not-so-bright about making mistakes and the importance of mistakes.
However, I sometimes get the feeling that mistakes still don’t go down too well and people are shy to talk about them.
But some people do talk, and this makes a very good read: http://standardissuemagazine.com/in-the-news/oscar-best-mistake-goes/
Life without mistakes would be boring. And somehow not very real.
