Thanks, Inchiki Gaijin.
Well, so the course is ok to try out, then. I was thinking of buying the bundle they sell, with the Reading Genius, Magical concentration and three other tape sets for $399 total. I'll probably just go for that Ultralearn course instead, and probably look into Ed Strachar's stuff later. The Ultralearn thing looks interesting, I've got a good gut feeling about it too, for some reason. Never heard of it before, so thanks for directing me to that.
The main reason I want to better my concentration is that I tend to struggle a lot with it when I read, which is funny since I've always been a big reader. I just don't read as easily as I used to when I was younger. (And I'm not even thirty...) It's gotten a bit better lately though, I'm using a few supplements and also changing my diet a bit, and the Sedona Method really seems to help it, even though I haven't released on that particular problem a single time. I'm struggling a bit with my health right now, but getting better, and when I'm well enough I'll start exercising again as well. Being in good physical shape can definitely help, of course. Win Wenger's underwater swimming thing is something I'll definitely try out as well.
Well thanks again, if you have any other tips I'll definitely be grateful for that as well. Enjoy your day.
