The worse thing about being wrong is thinking you were right, and all your intentions were right but because of things that you couldn’t determine at the time, it becomes wrong because of them.
The question really is should I? should I have been able to determine these things? The longer you ask this question the longer it becomes apparent that perhaps you couldn’t known these things.
What’s difficult is feeling outdone by ones lack of foresight into these things – beforehand obviously.
