Edit what you say when you speak to yourself. If you find yourself about to say something important in a negative pattern, edit it to a positive pattern.
If someone were about to say to himself, "That was stupid of me," he would be much better off editing this to say, "Be smart" or "Be wise" instead.
Perhaps he really did say or do something stupid. But now that he is aware of this mistake, he would be wise to tell himself how he would prefer to be in the future. Both of these positive self-statements are messages to make smarter and wiser choices and decisions. This is good advice to give to oneself.
If someone were about to say to himself, "There you go again. You are always making these kinds of mistakes," he would be much better off editing this to, "I'm glad that I realize that this was a mistake. I am strongly resolved to speak and act in ways that would be better to speak and act."
