I like the notion of the psychological immune system, this was kind of a blessing because you had an epiphany that I believe has served you well over the subsequent years. And for many of us, when we say yes, when we should have said no, the pain we experience is more minor. It may not be enough for us to really rewind, evaluate and make some changes. But we do feel resentful very often. Sometimes we need to just see it for what it is and not make the mistake again.
