One more thing... I know about langauge acquisition,.... that might be of note...

when we are children, our mind spends more time in a state of theta brainwaves... so if you can hypnotize yourself more often, which is sort of a hobby of mine, that can help you out greatly also...

try to use binuaral beats to bring your brain into this state and listen to some vocabulary cd or whatever... i have found this helps alot with vocabulary building...
