Re: Spirit and loyalty
in kids classes it is shown that using colored belts provides a 'visual' cue to build goals--something to look forward to and ultimately a reason to train and get better. I suggest a similar thought for people in general. It sound like you're in a rut because there are no examples of what a person could look like in ____ months if they keep training. For me, it was watching sempai do effortless highfalls and saying, "man, i cant wait to do that".
So, since you seem to be most into it, you should try to carve out xtra time with your sensei and rise in ranks and ability so you can be that person for others.
just my take.
