This is a method of choosing which skills to choose as Major or Minor. The principle is to choose those skills which you want to determine when your character will level up.
Enchanting - The character should level up as he gets better gear.
Light Armor - The character should level up as he sees more combat.
Mysticism - The character should level up as he gets better at soul-binding.
Security - The character should level up as he sees more of the world.
Restoration - The character should level up as he becomes better at preparing and protecting himself.
I took Long Blade and the remaining four magical skills as Minor (Destruction, Alteration, Illusion, Conjuration).
I don't want the character to level up when he runs and jumps around and talks with people and haggles with merchants. I think this approach to choosing your skills is best.
