This may seem cheap. But here are 2 very good skill leveling tricks for Elder Scrolls V Skyrim.
Stealth to 100
At the begining of the game. When you encounter the Bear in the cave. Go to the right, until you see a set of rocks you can jump on. WHILE SNEAKING. Jump on the rocks and face a while. WHILE SNEAKING. Run into the wall. Apply weight, or rubber band to the controller and level. It will take you about 2 hours to level yourself to level 100 this way.
Craft to 100
Just spam make iron daggers. buy lots of iron ore and dagger making stuff. Then run around making them until you run out and sell them. Make sure to do some quests before doing this, as you will use up like 1,000 gold pieces and lose a profit. Now just sleep for 2 days straight and repeat the process. Before you know it, you will have craft to 100.
