But I think I must give you an advice, although you may know it, but nevertheless:

- BEWARE not to break (shock or lock) something, Alvin!
It is easy to happen, but takes years to heal!

- BEWARE egoistical teachers. It is even more dangerous than breaking your bone – its like breaking the soul.

Those guys do a lot of marketing and everything (most clever of them do this indirect) to “glue” you to their lessons. Things like “The only right way”, “Path to enlightment”, “Belts”, “Masters”, “rules”, learning/copying without understanding, high training costs, japan/chinese/other words/sentences learned, but without translation/understanding.

I am not saying you should leave such clubs, but I strongly recommend a ninja/shinobi behavour there. Comply, but always have your OWN “head”.
