Help for Navy SEAL training?

I want to be a Navy SEAL and have ever since I can remember, I run, swim, lift, and practice being mentally/physically tough almost everyday. But I want to know what I can do to really prepare myself for training, I have a weight room, a 30 by 30 pool and there's miles and miles of open space in which to run and excersize in by me. So given this what can i do to prepare myself?
