I make mistakes. We all do. Mistakes are a part of our life we can’t get rid of.
What I learned through life is how common mistakes are. You’ll find mistakes in virtually every book, every article, every city infrastructure, every work of art. Imperfection is all but a given.
However, it feels like we grossly underestimate the likelihood of a human error. In what is probably our greatest mistake, we don’t account for human error. Not enough, anyway.
My experience taught me to account for human error in everything I do. Always have a fallback, always have a plan B. Assume someone will make an unimaginable mistake and mess up your plans. Because they will.
Human error is not going away. It is more predictable than human success. You can set your watch to it. Try not to set it wrong.
