We have learned that mistakes are negative while we were children at school and as we joined the work force. We are allowed learning mistakes as long as they are not repeated or don't cost to much. This is an attitude that assumes we could have prevented them through better thinking or planning.
But what are mistakes?
They are usually things that we only understand in hindsight as being errors in thinking as we failed to predicte future events and actions prefectly. It is only when we accept those errors as somehow being preventable that we can feel we have screwed up. Yes, we want to prevent major errors in judgement whenever possible as is sensible. But to try and eliminate all mistakes is not possible.
We should understand that mistakes will be made and realize that they will be part of making any change. Then when we make one we can adjust immediately and continue rather than having it stop us in our tracks as so many times it does.
Perhaps we should consider mistakes as a natural part of living and not blow them out of proportion when we make them as we will.
