Exactly, remember, you come first in all of this. Everything else should come second, if you don't take care of yourself...well, your essentially helping no one. That said, I don't think that you should take care of yourself simply for the sake of others, you have to set aside some love and care for the sake of pure self-respect. That segues into my next question, are you GMing any RPs other than those on PC?
I see what you mean... Perhaps it's a matter of kicking that habbit in the face to fix my muse. Guess I tried to sacrifice a bit too much for others, until there was nothing left for myself. Can't really help others either way if I can't help myself.
I don't think you need to do that; after all, you practically brought up a generation of RPers, already, directly or otherwise. You made a guide that is still one of the best and most in-depth apparatus one can go to for Roleplaying tips, in a sense, it's a real hand holder (I probably wouldn't be that good of a roleplayer without it). Not only that, but you go further out of your way to help people in need via in the discussion thread, and even those posts are rather sizable, and then there are all of the apprentices you molded into respectable roleplayers; those are some pretty big achievements.
I'd agree about PC suffering from muse problems, but you're doing too much, already. People already know who you are and how helpful you are, and the impression you've made on PC's RP community; this is one case where I'd actually say you've no need to strive towards motivating others or raising morale. You've already got a lot on your plate, leave PC's improvement to us.
...Granted, I do realize that I'm actually telling to do less of what you love to do, and really it's not my place to say this, I don't feel that you should do something such as this out of obligation, and it'd definitely free up time for other things you may be interested in (or sleep or school) if you did take time off from PC or visited less.
Well... alright. I've got a handful of off-site RPs including chat RPs, I make music, administrate a website, I've got school, and...honestly? PC here is the only place currently suffering from such extreme muse problems.
I feel like perhaps it's the atmosphere. I feel obligated to try extra hard, obligated to try and impress, obligated to set an example even when I'm not feeling up to trying hard.
They're related, as your health improves, so will your muse, I can almost guarantee that. Your brain will work better and your thoughts will flow much more smoothly if you get more sleep. Heck, even if it only affects your health, that should be a good thing in and of itself. Granted, I know how you feel about that amount of sleep being exhausting, but your body will adjust. I'd say that you need at least 6 hours, and don't go pulling all-nighters on RP posts, it's bad for your health and for your RP quality. If I may suggest, try spreading out the time you roleplay more, maybe even starting a post and then finishing it at a later point, maybe even another day. Just don't drain yourself.
Another thing, if you feel writer's block coming on, stop before it gets bad. It's not good that you torture yourself like that, do some sort of stretch or exercise or just take a nap. I know I've already said this several times, but not just me, but the PC RP community as a whole doesn't want you hurting yourself like this; you're a pretty valuable member after all. Pace yourself, relax, rest, and just stay safe.
I'm already playing tennis and arranging music and doing various other smaller things as hobbies though. D; I guess if I could find the perfect video game to occupy my mind for a bit each day. But I'm cursed with a competitive attitude and mental limitations that cripple my ability to effectively compete, so I kind of suspect there is no such thing out there for me.
I also need something more active than watching TV, or my mind will fall asleep from lack of stimulation. I guess I could sleep, but somehow I don't think that's going to help my muse so much as it will help my health. Plus, oversleeping is really bad for you. If I switch to 8 hours of sleep it is going to be murder on my body, and I will feel exhausted already when I get up.
Just be careful, okay? I know you're having fun, but it's not good that you deprive yourself of sleep and the like for the sake of it. I really think that you should actually strive to find other hobbies that take up your time and actually force you to RP less. You may be very deeply invested in the RPs but they're not good for you, and as much as you love it, I really think that you should worry about yourself more than your hobby.
Roleplay will always be here, and really, your muse can only recover from your cutting down, and in doing so, you'll start to find it to be more fun and you'd just be plain better at it; it's a sort of "you can have your cake and eat it, too" type of deal, it really only can help you. You don't need to stop, outright, but just find other things to take up other hobbies and sleep more. Do yoga, learn Japanese, take up biking, find a good show to get invested in, just something that you enjoy, not only would that improve your quality of life, but you could also bring your experiences back to roleplaying.
But as I said, just be careful; try to balance out what's fun to you and what you need, no one wants you to deprive yourself for the sake of their roleplays, and even if you do enjoy them so much, just consider how this is affecting you.
