Your Character is not your Class Nor Your Quests (Guide)
From Hofborg
It is generally held to be true that the role-play of your character is separate from both your game class/abilities as well as from the quests you've done in character.
You are neither required, nor encourage to try and match up your character's back story with the entirety of the ESO Quest lore, nor should your character's power level be based on your in game class and game mech accomplishments.
In fact, doing so, may generate pushback and possible accusations of having a "mary-sue character" or "power gaming/superman rp".
Consider specializing in one or two craft abilities, not all of them. Consider adding some quest back stories from your characters natural region rather them all of them. And remember we can't all be the hero of Skyrim!
