I think "show yourself" might have double meaning in this song.
The first would be what someone might yell out in a dark forest when they hear a sound and think someone is there: "show yourself!"
The second would be what someone might recommend to another person in order to teach them how to do something: "I don't know, show yourself how to do it."
As such, I think the song might be saying to both "show" (reveal) your true identity and to "show" (teach) yourself how to do things. Be proud and independent?
