We got some galvanise, covered it over, and called it a dojo. We paid TT$6 a month for the space,” Don Jacob recalls. He was only 15 years old then, and charged students TT$1.50 to learn his martial arts fighting system, which he called Don Jitsu-Ryu. Until he acquired this headquarters, Jacob had traversed Trinidad on a Chopper bicycle which he bought for TT$25, teaching his techniques and gradually realizing that he could actually earn a living by doing what he loved.
