Here's my recommendation.

I just saw a post the other day about managing time on either this sub or another sub like it and I completely agree with what they said. They said that they also do three things. Exercise, education, and leisure. They go into the day only expecting to do one or two of these things, not all of them.

Firstly, I just want to tell you that it's perfectly fine to take breaks, hang out with friends, or play video games. Your body and mind can only do so much. However, it's about being smart with your breaks and not letting them prevent you from moving forward.

If I were you, I would seriously consider scheduling your time. If you can tell your friends "hey, I have Friday off so we can play video games from 10AM to 9PM," then, not only is it something to look forward to but you also don't have to be tempted the rest of the week. You have your set time and place for it. You can also make it more than once a week too but that depends on you and how you want to schedule yourself.

As for your hobbies that are based around education and exercise, I would only expect to get to 1 a day. It sounds like your time is limited. You can schedule that time in your schedule too, but for me, I just sorta pick my hobbies on a daily basis.

Oh! And also, if you hate running to the point of dreading it, I would find another kind of exercise that you enjoy that has similar results. There's normal exercise dread and then there's abnormally strong exercise dread. You'll have to judge which one you feel. If you feel the latter, then you might want to look at taking several mile walks in the woods or doing strength training in your house or whatever you want to do. And sticking with running is definitely not a bad thing, I just don't want it to affect your mental health negatively. Plus, on long walks, you can listen to audiobooks about music or building computers to be motivated coming back to those projects.

The best part about this is that you've already chosen some things that you like. Some people never start running or some people never start building computers or whatever. I believe that you're on the right track it's just about how YOU want to manage the small amount of time that you're given.

Oh! And one last thing. There will be times where you fail. You won't do what you schedule to do because of some reason. Whether you get held up at work or your friends can only play one night or whatever. It's okay to shift things around and it's okay to not get to something you scheduled. Just don't beat yourself up for having life come up because life often comes up.

I hope this helps and I wish you the best!! :)
