i suggest you get you endurance up as fast as you can(the sonner its 100 the more health youll have in the long run)
im also 'powergaming' at the moment and i get myself an enemy, block his attacks until my block is 10 levels higher, then i get +5 of another attribute(mostly personality as i train my mercantile five levels every level as its the lamest skill ever, and ive got illusion and speechcraft in my majors) and then i level my luck. this attribute is often overlooked! i increase my luck nearly every level because when you get 100 of every attribute(except luck of course!) your major skills will be so high that you can only level up a few times and then youd have to go to jail to DECREASE(i so hate that word) your major skills to level up. ive had an account of level 46 with 100 of every attribute and the last 5 levels all he had to increase was luck.
but it seems you already have a pretty nice account there!
little question: what race and birthsign are you?
mine was altmer under the apprentice birthsign, which made me have 400 magicka
could cast pretty nice 'home-made' spells with that one!
