I wanted to read the book Unlimited Power: The New Science of Personal Achievement last year. Then last week I was brave and I decided to buy that book. I was wrong I could understand easily the pages I read. I’ve been using SuperMemo for 4 moths and it helps me to remember a lot of words and grammar structures. I’d to search just two or three words per page. I think that book is very interesting. I've been learning English since January 2007.
Book Unlimited Power
Omg, I read that book a month ago! Except I had the original edition ;)
