I've challenged myself to practice the new Mantis form I've just learned 200 times by the end of November, in a bid to get it into my muscle memory for the long term.
Found martial arts a few years ago when I was already old enough to know better.
Despite this I now try to dedicate as much time to Kung Fu, Tai Chi Chuan and associated arcane philosophies as I can given a husband, two young kids and a full time job....
