Go boldly amidst the noise and haste of LFD, and enjoy what peace there may be in silence. As far as possible without grinding, be on good terms with all factions. Speak your strats quietly and clearly; and listen to others, even the l33tsauce and the preeners; they too can serve as examples.
Avoid loud and spammy persons, they are vexations to /Y. If you compare yourself with others players, you may become vain or bitter; for always there will be greater and lesser gearscore than yours.
Enjoy your achievements as well as your gear plans. Keep interested in your main, however boring dailies may be; this is a real asset in the changing endgame raid tier.
Exercise caution in on the AH; for the world is full of trickery. But let this not blind you to what deals there are; many persons strive for undercuts; and everywhere life is full of profit.
Be yourself. Especially, do not feign affection. Neither be cynical about your guild; for in the face of all aridity and disenchantment it is as constant as the stars.
Take kindly the counsel of experience, gracefully surrendering the gear of youth. Nurture PvP gear to shield you in sudden misfortune. But do not distress yourself with dark imaginings. Many wipes are born of fatigue and loneliness.
Beyond a wholesome discipline, be gentle with yourself. You are a child of the Titans, no less than the Gnomes and the Dwarves; you have a right to be here.
And whether or not it is clear to you, no doubt lore is unfolding as it should. Therefore be at peace with Metzen, whatever you conceive Him to be, and whatever your labors and aspirations, in the noisy confusion of life keep peace with your Transmog set. With all its sham, drudgery, and broken dreams, it is still a beautiful virtual world. Be cheerful.
Strive to cap your VP.
