I’m going to start prioritizing routine over social life. Is this a good idea?

I've always struggled with friendships. I mean, I've made friends in every era of my life so far, but they've always came and went. Either because of moving or a lot of times just growing apart. Right now I only have 2 strong friends, one has been fading because of differences, but I'm trying to make it work but cutting down how often we hang out. The other one, I only hang out with every other month. And, I am well aware that as I get older, friends will more often have families at the center of their lives so less time to spend with me. Some people say that therefore I should relish the fact that I have friends to hang out with while i can, but honestly, I need to have my own priorities straight.

I want to start going to bed around the same time every night. Whether it's during the three days that I work (I have to wake up at 5:15 am for work) or the days off (I usually get up whenever, but usually around 9-10 am). I try to get 7-8 hours every night, too.

I also want to workout more often. Right now I miss days a lot because of disorganized schedule. I feel like if my schedule was a little more organized, I'd be hitting more days. The thing that's interfering a lot is random wake up times and bed times, I think.

It's something I want to try out. But I'm somewhat afraid of putting more boundaries on friendships and hangout times, because my social life is already very limited. But… ultimately, I feel like this is the best time in my life to do it, having only two friends and one I'm somewhat at odds with, the other I only see occasionally. I need to assert that my bed time is 10pm, so I can wake up at least 6-7 AM on days I'm not working.

Do you think I'm being obsessive here and this is just an unnecessary block in my social life? Or is it actually something that will help strengthen my routine? I'm a very routine-oriented person. Between working out 7 days a week, keeping up with house chores, spending time with my hobby (writing), and whatever else, I feel like I need this type of structure to better fulfill these goals.

I will always keep an eye open for more friends along the way as I move through life, and I'll remain hopeful that even with this somewhat strict routine, I will still have room to have friends and maybe a partner some day.
