Imagine who your would like to play act as a character, then pick the ingame features (appearance, race, class) that suports your role.
For example ...
your favourite movie character of all time is Palpatine ... and you think being able to cast lightening would be awesome.
... well there you have it, a humanoid sorcerer tweaking your appearance as best you can to
the use the overload as often as you want
be a bad guy, choose the quest line choices that reflect a nasty character
... its not a competition .. its what you enjoy doing
btw .. this is the archetype of my main toon
Everyone knows the phenomenon of trying to hold your breath underwater - how at first it's alright and you can handle it, and then as it gets closer and closer to the time when you must breathe, how urgent the need becomes, the lust and the hunger to breathe. And then the panic sets in when you begin to think that you won't be able to breathe - and finally, when you take in air and the anxiety subsides...that's what it's like to be a vampire and need blood.

First, come up with a character. Find out what makes them strong, in what ways they are weak, and build their personality. Once you've done that, build a personality for that character. Really flesh them out. Let the character exist in your mind, and give them a real feeling set of traits. Are they perpetually unhappy? Are they cheerful? Maybe they're a kleptomaniac Bosmer that just can't stop getting caught.
Just come up with something, then run wild with it. Enjoy your character, enjoy what you're doing, and have fun.
