I'm not quite sure what you're after. I'll try and answer what I think you're asking though.
Jiu jitsu is a massive sport in terms of how much knowledge you can acquire in it. You start off with no knowledge and you're losing every single day. Most people will drop off and find an easier sport or hobby.
The people that do stick around start picking up more and more information and building their own game. They'll eventually start winning more and more rolls in the club and learn more about why they lose when it doesn't go their way.
The community is great. I believe this is a function of spending so much time in such close proxity to each other, literally face-to-face. There's a lot of trust between training partners.
Competition keeps it interesting and makes sure techniques and games are "honest". There's no point in learning or teaching something if it never ever works. There's a large analytical community that will look through matches, post write-ups and build the collective knowledge.
There's no "good" body shape or particular style that works for jiu jitsu. Generally bigger people will beat smaller people but if there's a skill gap or a few special techniques then the match can go the other way. This means anyone can dedicate the time and just get better on their own schedule.
I don't know what other hobby could replicate that. It would probably be a sport that doesn't rely on a team but instead of individuals testing themselves on other people. Weight lifting could be appropriate. Maybe something like infosec CTFs or Incident Response challenges. You're not competing against other individuals but all solving the problem in your own way.
Racing/driving could be another one but that would be hard as a wheelchair user.
Honestly, I don't know enough about life in a wheelchair to say what is or is not relevant.
You're right. Good habits are important. Routines relieve our cognitive capacities and help us to get through the day faster and more efficiently.
But the best of all good habits was to stop hoping that something, a change or a habit could have a massive impact on my life. So I ceased to hope and believe.
Be strong from yourself and accept that there is not THE answer or ONE life changer.
Oh yeah, the lingering hope for THAT ultimate apps or THAT ultimate productivity technique that will finally change your life, postponed what you can do RIGHT NOW for things that might not even existed.
Anyway, after searching for ultimate technique for a long time, I found that the answer (for me at least) is as simple as simply wake up early and do most important things first (for me recently, is exercise) before shitstorm happened — the classic, proven wisdom that I used to refuse to do because it’s not ULTIMATE enough Haha. "How can that conservative routine cope with fast-paced digital lifestyle nowadays!?" What a fool am I.
Your doubts are well-founded if you intend to use the project as a further dependency for other projects. Arabica is intended to provide a kind of early interim solution to bundle the necessary technology stack for publishing.
