Whats the best way to get good at grappling (jiujitsu) really fast? Anyone know any sweet books or techniques?

There are no magic bullets or short cuts to becoming good at martial arts. That is why it takes many years to become a true master. That being said books, videos, ....etc. can only be really useful to fefresh things that you already know. No one has eve successfully taught themselves martial arts. It requires much training and correction under the guidance of a good instructor. Also without a training partner, you can only mimic moves.
