Okay, why Green Lantern?

Why Green Lantern? I plan to go into this in more detail someday, but the short reason is, because to be Green Lantern, you just have to be the right guy. You don't have to come from another planet. Your parents don't have to be killed in front of you. You don't have to be born with genetic mutations, or irradiated, or be bitten by something that was irradiated. You just have to be the right guy. You have to have a strong will, and you have to be capable of overcoming great fear. If you have those qualities, and are honest, you too can be a Green Lantern.
