Observation: The model of development in Jiu jitsu ought always to be as close as possible to the classical model of development in science – of the interaction of hypothesis, experiment and observation and assessment of results in a never ending rotation that gives provisional but increasingly better answers to the questions you ask. When it comes time to asses the worth of given moves, the merits of your training program, your performance of technique and tactics, nothing beats observation. As an athlete you must keenly observe your performances and make adjustments based in the feedback your eyes give you. Training in itself is is the most important thing in the short term, but for long term progress almost as important is observation and assessment of that training that allows you to bring the results of today’s workout to tomorrow’s workout so that a compounding effect can be attained – only then can you grow over time to the level that you aspire to.
