As students, not only in our respective home faculties, but also as disciples of Judo, the most direct way of bringing「精力善用」into our lives, I believe, lies in the following keyword: APPLICATION. Like sponges soaking into the sea of knowledge that is added to everyday by our university professors as well as OBs who take the time to come down and instruct us in the finer details of particular techniques and styles, it is praiseworthy, of course, to absorb all that we can, but over and above that, what is of paramount importance here is to not only temporarily take in, but to mull over, deconstruct, and finally resynthesize what is being taught to us as our own knowledge. After all, there is no point in being a super absorbent sponge, only to soak in, squeeze out, then soak in again, because nothing winds up retained in the longer-term, and capacities stagnate with no real work being done (the sad truth is that this is an inevitable part of our lives, what with tests requiring us to cram ourselves to our brims with knowledge, only to empty everything out and start anew at the coming of the next semester).
Easy as one, two, three:
Like the 反復 that we so often utilize in Judo training, tossing and turning newly learnt ideas in your head is an important process that lets you not only take stock of what you have achieved thus far – it also allows you invaluable insights into what to focus on, going ahead!
It is impossible to eternally retain all that you learn of course – it is, however, not only possible, but quintessential that we all be active consumers of knowledge, stripping down what is dispensed, and taking in what we feel will enrich and strengthen us. This applies not only to our studies, but also to the art of Judo that we so adore and dedicate ourselves to. We will definitely continue to strive hard, and discover for ourselves, the sort of Judoka that we are destined to become.
