Having seen all those things come and go I realised the same old art is still sitting there letting the fashions and fads wash over it like waves at the beach.
There is a nice discussion on fads like â€œpressure pointsâ€, â€œbunkaiâ€ and â€œunderlying principlesâ€.
Nice sum up as well
There is no need to “train for this” or “train for that”. Training for itself and for your own purpose is good enough.
