You can hardly call a job the basics teach in the hall in novice like dodging aoes or throwing healing spells, we are not talking of 15 hours per day trainings to get the first world kill on the last raiding boss. And even that would not be called work by most of those who do it for fun or competition.
I suppose that at the very beginning of the first stage of Super Mario Bros you keep pressing only right to die repeatedly on the first goomba, shouting "Why ? Why should i bother pressing another button to jump ? It feels like a job !!!" XD
