Theme From "Greatest American Hero" (Believe It Or Not)

The speaker describes a sudden change that feels almost impossible: life has lifted them “on top of the world,” and they feel freer and happier than they expected. At first, they can hardly recognize this confident version of themselves. The mood is joyful and amazed, with a brief turn toward romance when the speaker says they are “falling for you.”

“Walking on air” is an expression for feeling extremely happy, not a literal claim that the speaker is flying. “Hit me from out of the blue” means the change came unexpectedly, like a surprise. The image of “flying away on a wing and a prayer” suggests taking a hopeful, uncertain leap, relying partly on luck or faith rather than certainty.

The lyrics leave the cause of the transformation open. It may be a new love, an unexpected opportunity, or a broader change in how the speaker sees themselves. The line “It should have been somebody else” hints at disbelief or feeling undeserving, but the repeated realization “it’s just me” suggests growing acceptance. The speaker’s excitement is sincere, though “too good to be true” shows that some doubt remains.
