Firstly, "my determination glows like the moonlight in the dark" is just a plain badass line. Excellent job. "I take my rightful place because all I've earned is rightfully mine" is another great line, and one which really holds a strong truth: people are judged by what they've earned, in terms of deeds, works, positions. "Earned," I think, is the operative word, because one has to work to earn something. What I've essentially taken away from this poem is that to amount to anything--to be a superstar--you must put your entire being into it: soul, mind, and muscle. And whatever station you arrive at, it truly will be rightfully yours, because you will have worked for it. A very inspiring poem.
