and im back on here once again , why can't i settle with one character in Skyrim ! !

my reasons why i can't settle is cause i keep restarting i can't pick between a Mage , Warrior or Assassin all because of these reasons

Mage : i feel like im missing out on some fights cause im always far away from the battle summoning things and using fire bolts

Warrior: its all about hack and slash it gets boring after a while but i enjoy using heavy armor and making my own weapons and armor ,thats why i like warrior

Assassin: dark brotherhood armor . . why use any other light armor , thats about it i love sneaking around but i wanna use other armors not just dark brotherhood armor

i do not want to be a hybrid character cause i want to do three playthroughs of this game , which character should i be or how can i make each class more fun?

ps i do mix things up a little bit , with a mage i use a sword but try to stick with magic , with warrior i do sneak around a bit not alot though , and assassin i carry a sword or a axe if i end up failing at sneaking
