This song is a good example of the dichotomy between self-perception and self-awareness. Even when we think that we understand why we do the things we do, are we really aware of the consequences? How do we deal with misunderstanding or being misunderstood? What is intentionally kept hidden and what is unknowingly kept from others?
One line that hits me hard in this song is when he sings "...know just what I got in this good thing I've found." I'm not sure I know why though. There's a lot packed into every line of this song, but this line stands out to me.
