I think reinventing your training and approach is important. Firstly understanding the deeper stuff of what drives you to train, and what you really value about it and what you get out of it is important, but also being creative in exploring your art.
There can often be a very stoic, clinical approach to training in which people say you just gotta repeat things over and over and over, and whilst it's true on a level, there are other approaches and methods in which you can train things.
Some of my sessions at home are very planned, line by line of what I want to work on, and others are completely and totally spontaneous, whatever I'm just leaning towards in the moment, and honestly these have been some of the best and most productive sessions. Because you can train something, and it brings up a natural curiosity within a technique or movement, and you delve deeper and explore it without a script prior. Totally experiential exploration. It's like being a disciplined loosy-goose haha.
Both approaches are self-directed, but one is simply more intuitive.
Or you could just go back to karate. Yeah. I say you just do karate. Guys, I think we can bring him back
