Just remember, irl stuff is always more important than online stuff, no matter what :P I also forgot what it was like to be in school (though we got out in June...), which is why I've been considering only being active in a few RPs at a time.
I mean, hey, if you're super organized and have time for irl stuff and RPs, then that's good! But if you're like me and kind of unorganized, then you shouldn't force yourself to join/make so many RPs. Heck, even if some seem really interesting and you really want to join them, you should consider your health and business irl before jumping the gun and joining them! 'Course, if you're 150% sure you want in on some RP, there's always the option of dropping another RP. You can't have everything you want all the time, you know? And if you're afraid of disappointment, don't be! People need to understand that you have other stuff going on that cuts into your RPing time. And if they can't understand that, then they really don't have a life, if you ask me :P
