"A man who has one finger pointing at another has three pointing towards himself" ~ A Nigerian proverb
We are not perfect; we make mistakes; sometimes things don't work out the way we want; they simply go wrong. Think about a team work that didn't work out. We usually have the tendency to look outside of ourselves to put the blame on something or someone, don't we? Couldn't the outcome be different had you played a different role? Most importantly is it going to help pointing at something or someone? Probably not. Think about the above proverb before you point your fingers next time.
