Query: awesome book!!

this is one of the best motivational books that brian has written.the others are goals and maximum achievement.by following things you learn from his books and audio program i have been able to increase my productivity by 4%per month.brian has been the biggest mentor that i have had and i can't help but share his concepts to people i meet so they too may gain from it. i have all his books,read them over and over,though repetitive ,repetition helps you remember concepts better.get his books,read,apply them and watch your future get better.
