Probably start collecting spells and cataloging their differences compared to ob.

Lawl...

Me? Depends. If I get a clear order like in Oblivion to "IMMEDIATELY get this VERY IMPORTANT amulet to Jauffre in Chorrol!!!" then I will do that. Like immediately. Immersion-breaking for me if I dont. But if I get a more laid down start (like in Morrowind, "Meet up with Caius and give him this package, do what he tells you." I will propably 1. check the first best ruin or cave for enemies and loot or 2. get some quests from the locals in the nearest settlement and do them.

I'm going to destroy everything in my path and find some better equipment.

I'm going to walk around for hours just taking in all the sights and familiarize myself with a portion of the map. Then I'm going to be relieved that Skyrim is finally in my possession!

I will create the (son of) the most badass wizzardess that ever lived!

I will take things from peoples houses and put them in barrels

As always I will talk to people, and then im gonna find a nice little tavern and listen to conversations, and try to pick up any info about the surrounding area. I will then find a weapon smith, buying a cheap bow and some arrows, along with a longblade. Bying some clothes or light armor att another store, and head into the wilderness.

Experience the world. Steal stuff. Maybe do a couple side quests and join a faction. I plan to skip the main quest first time around.

As soon as I get out of the tutorial, I'm heading to Falkreath to see what I can do there. After all, according to my character's history, that's where he lives.

I'm going to explore a bit, spend hours on creating a new member of the Lenoir family (my main character is always a Breton with the surname Lenoir) and make him as sneaky as possible.

Then I'm going to locate the Dark Brotherhood and join (if possible, they hinted that it would be back). So yeah, that character is going to follow in the footsteps of his ancestor.

make sure my character looks good and in light and dark but changing around the options in character creation

probably will spened 40+ minutes on character creation

and then exit the tutorial dungeon and find the nearest town/city

A wise man once said... "It will happen"

The same thing I always do with Bethesda games when I first start, pick a direction and start walking.

The first thing I'll do once the character creation is over, is just wander around looking at the scenery and all the little details. I'm pretty bad about this as I can waste an hour just looking at the world and what not.

I'll stop in middle of main quest and become the master of all factions(if this will be possible).And of course i'll make house .

Find the Dark Brotherhood and join them, then find out how to become a vampire. Feed. Kill. Repeat.

spending alot of time in the wilderness

Find the Dunmer city and get to stealing. Unless they're refugees, then I'll just find some random well-off people to rob.
