Just one will not make a line.

As to your actual question, you should probably check your state's laws about wills. I don't know if Louisiana allows minors to write a will for themselves, and you will definately want one saying that your body is to be turned over to the cryonics agency of your choice (usually either the Cryonics Institute or Alcor) upon your death. You'll also probably want to get a wrist bracelet or dog tags informing people to call your cryonicist in the event that you're dead or incapacitated.
