As a competitive person, I do not want to be mediocre at anything I do. I want to be so good at my job that I earn a bonus at annual review time. I want to be early instead of late. I want to be the great mom who comes to all the parent-teacher conferences and always turns in signed permission slips before they're due. Heck, I even want to be in the front of the pack in traffic on the interstate.
I have worked hard to achieve all of this perfection -- and failed miserably. One thing that I've learned through my adult life is that any time you think you're the best at something, 10 other people will come along who show you up. I do the best I can, and I have to will myself to be satisfied with that. If I tried to be the overachiever, then I'd probably stress myself into a heart attack.
It's the same way with World of Warcraft. I want to have maxed-out professions with all the rare recipes. I want to have the highest GearScore, top the DPS chart and hold hate perfectly with no runaways if I'm tanking. I want to get all the achievements, have the coolest vanity pets and ride in on that rare mount no one else has. Yeah, that's what I wish for. But, I am never, ever going to get there.
