The line that stops me is "love begins when we recognize our own value." That order matters. So much of what we call seeking love is actually outsourcing the worth question to someone else and hoping they answer it for us.
The thing I keep relearning in my own life is that the feeling of being a missing piece usually isn't a fact about me, it's a story I picked up somewhere. Naming it as a story, not a verdict, is what loosens it.
