And none of them will ever work. Magic is the energy within nature and the natural world. Thus, because it's part of nature it's governed by nature's laws. It can't be used to change your gender, it can't be used to change your race, it can't change your species, you can't use it to control the elements or the weather, etc. It can't be used to reach unimaginable odds. As practitioners of magic, we must first learn to accept and understand its limitations and its basics before we can truly begin practicing or understanding it.
That being said, why would you want to change who you are in the first place? Can't you just be happy with you? We are all special in our own way, we are all unique. Be happy with that, be happy with who you are and it can do wonders for you in the long run.
