Usually, when I solo, I concentrate on my stone usage and skills .___. It works for me somehow, haha. I look for the amount of stones I use without resting and memorize when I need to stone so that hopefully the ratio of hp to sp stones is high on the hp end. And then I count the seconds of cooldown and try to chaincast my skills so that I can kill continuously. It works miraculously for quests that call for an enormous amount of a SINGLE BLASTED mob xD
I also have a habit of putting my earphones on but not listening to music, just the effect noises of fiesta o__o Putting on the earphones makes the mouse clicking and typing sounds dimmer, which is somehow appealing to my ears = =
