I could see myself doing any of these:

• Fletcher - Realistically I could see myself doing this, though I never got into archery in my life (classes, shooting a bunch, ect) in the world of Elder Scrolls it is my favorite weapon type so just crafting and learning about arrows could be awesome. Once I was good enough I could hunt and sell the meat as well or even continue and do my next possible job.
  
• Mercenary - Pay me and I'll help you out with the knowledge from above I should be pretty capable of holding my own in a fight and being able to keep an eye out on any one who pays me to do so.
  
• Bartender - If all else fails I could always pours some drinks, and sense I don't drink myself I would drink away any of my product.

I will be an evil sorcerer that lives in a tall black tower where there is a thunderstorm and lightning strikes all day! I will have a servant named Grima Wormtongue!

studying magic is what I'd do

What would I live like? Probably like a farmer, just like the majority of the population. Maybe a hunter or a fisherman. What would I want to live like? Like a king, of course! Like a king in that I get to enjoy luxury, comfort, and wealth without having to deal with wars, court politics, and managing an entire hold.

I would live with the graybeards cause I feel safe. I'd live in proud spire manor and start a general store in solitude.

Cheers

Become a powerful Mage, extend my lifetime indefinitely with magic, use magic to assist recolonization of Vvardenfell, pay tons of assassins to take out the heads of the Dominion.

Does your general store have a good supply of Apples? I'll be traveling to buy nice fruit and berries for my pies. Is there a nice Inn in Solitude?

I would either take the path of the Companions or i would join the College of winterhold.

I'd probably study at the College of Winterhold, and then become a court mage to further my studies.
