"Like cheating on a test, ignoring a friend’s phone call, wallowing in self-pity, or eating a pint of ice cream in one sitting, being wrong feels the worst when someone else is around to witness it. Unlike these things, being wrong is unjustly stigmatized as unacceptable. Everyone answers a question incorrectly now and then, but it’s the shame associated with being wrong, especially in front of others, that harms us more than the fault itself."
We will never grow if we don't make mistakes and then learn from them. I am sure Bill Gates and James Dyson would agree. Look up any interview with them as they talk about their products.
