Boxing was always mine , I’m way too old now mind but I still do a bit of training and it helps my focus . As
@ForeverBlue92 has mentioned anything like that is great , he’s clearly significantly more experienced than me , but I signed up for some genetic MMA stuff a few years ago and still pop in and out and as he said you might well find that rush there . When you talk about not having the dedication firstly that doesn’t come over night and you’ll know that having spent years at your judo but also you don’t have to do it to compete or look at any kind of serious progression just start by looking at it as something to help your fitness , occupy an hour or so and help with your overall physical and mental health .
In reality though any form of exercise can probably give you something and given what little we can glean of your personality you seem like you’d focus on it and enjoy the pride it brings . You’ve taken The first step so you should already be proud of yourself .
As Fred had said , it’s a little oasis of openness and friendliness which goes from topics including food , puns and the usual Everton nonsense .
As regards you being well read that’s something to be really proud of and it’s also something easy to fall out of the habit of but what a fantastic escape it can be . Maybe that’s something you can try and set aside some time for once you start to find your feet.
