"mea culpa, mea culpa, mea máxima culpa." – You don't need to beat yourself up when you make a mistake

Often the ability to admit that one was in the wrong can very quickly lead to productivity. It is expected that any person will make a mistake once in a while, but it is essential that a person be able to realize, accept, and do their best to remedy their errors once realized or pointed out.

Inherent human nature dictates that no one is perfect. It is simply not possible for a person to avoid making a mistake or two from time to time. Yet admitting a mistake willingly can build character and makes it possible to react to the error in a very productive fashion. This can help alleviate guilt and distrust within the group and helps to foster a more collaborative environment.

You don't need to beat yourself up if you make a mistake and seeking punishment for a good faith error of others quickly blurs into a witchhunt. A much more reasoned and productive path is to seek to repair or mitigate any damage the error may have caused.
