Hey, Merry Christmas! I got a GameCube! I'm 30 years old and I act 14.
There's an old book called "Silva Mind Control Method" which I found to be good for relaxation, focus and concentration. I would not buy anything more expensive than the books because the whole alpha state thing is no big deal. Deep breathing plus Tia Chi movements do the SAME THING. There are 10000000000 ways to do the SAME THING. It does not matter WHAT you do to increase your awareness or whatever, just don't spend alot of money learning it like I did.
