I guess it's easier for some than others. I can relate to being scared, the whole flight or fight... I run. It's been ingrained into me since I was a little girl. But as I got older, I got way more assertive too. (Maybe little too much I'm afraid. LOL)
Some people just don't like examining themselves, because it can be quite a difficult process- or they don't want to face what they know to be true. There are many reasons why people duck in the shadows, rather than holding up that mirror. They are afraid of what they'll see. Others find it easy, and enlightening. I find it a mixed bag, myself. I have surprised myself, that's always good. And then, yes, I can be pretty damn ugly too. And I think that is what discourages people. It's a preconception, I suppose. I was afraid too- that whole being hard on myself, and stuff.
People don't usually equate that with their marriage or spouse either. They don't usually see that butterfly effect, how one things effects another, or vs, ya know. It's diffidently different perspective than all that I've been taught before.
