Fastest way to level up skills in Skyrim! HD
To get the additional 120 stamina you need: The Mask of Rahgot http://elderscrolls.wikia.com/wiki/Rahgot That will add 70p and then you need to travel the markets in search of boots(I found heavy armor steel) that will give you plus 40p to stamina. I found a merchant in Windhelm, you might find it elsewhere. Try to be at least level 10 before searching! Then, just find a ring and an amulet that will add to stamina points and you are set!
