Spend all the gold after purchasing a house to level the Heavy Armor skill.I have a love / hate relationship with the Elder Scrolls games.

Atronach scrolls are very useful before you get a staff.

Make sure to open all dragon lairs on the map so you can revisit them when they respawn.

Killing dragons is a good source of income as well.

This is the best income you can get without trading.

I usually get 5000 gold ASAP to marry someone.

The chest, hand, and foot pieces will need to be updated though, when you get a higher tier armor.

Use the Enchanter's Elixir from the place where you fought Durnehviir and craft your endgame gear.

Level Enchanting to 100 and get Seeker of Sorcery and Ahzidal's Set to boost your enchantments.

Go to Neloth and do Reluctant Steward for him.

After that start doing the Dragonborn DLC up to the point of Cleansing the Stones.

Progress with the main quest and talk to the Greybeards.

Save/reload before the entrance to roll the one you need. There is a Falmer in the Inner Sanctum that can have any Expert level spell book. It should not be an issue, provided that 1 can be taken from the Arch-Mage's quarters or even 2 if 30 days pass.

Farm Mzinchaleft, Nchuand Zel, and Alftand to get 120-130 filled soul gems.

Every time you level enchanting, don't forget to switch to the Mage Stone and sleep in an inn to get 30% boost to skill growth. Get Serana and keep her as a second follower for a while. Collect all the filled soul gems and pieces of clothing on the way. Save/reload before the fight if none dropped. In Mzulft, Dwarven Spheres can drop Greater Soul Gems that you will need to craft an Atronach staff. Make sure to get Firebolt when you enter it.

Complete the Book of Love quest and take the Lord Stone.

(20 to get to Windhelm + 250 to get to Solstheim + 500 for the guy) He is the best mercenary you can get for now. Weapon enchantments should be the following:

Chest - Fortify Destruction/Fortify Health.

With the Unofficial Patch, you can do this, provided you have Seeker of Sorcery, Enchanter's Elixir, and Ahzidal's Set to boost the skill.

Hands - Fortify Heavy Armor/Fortify One-Handed.

Chest - Fortify Destruction/Fortify Destruction and Magicka Regen.

Ring - Fortify Destruction/Fortify Health.

Amulet - Fortify Destruction/Resist Magic.

You will need the following enchantments without the Unofficial Patch. Use the Black Book: Waking Dreams to remove all the points from Enchanting when it is not needed. You can see 37 perks there, yet the maximum level will be 35. I also suggest using daggers or a dagger in the off-hand and a sword in the main hand. It may not reach 567, but will be pretty close without smithing. We need to cap magic resistance and place a second enchantment on weapons. 98% of the time your damage will be lower only to get higher during episodic boss fights. You may say, 'I need potions for bosses only'. Gathering ingredients is not an easy thing, and refreshing the store inventory is not a quick way for finding those four ingredients either. 10-20 potions take hours to make, but they get consumed in 10-20 minutes. Everyone I saw on the YouTube says, 'Make a strong potion.' I tried that. So the lower your level is, the higher damage you deal relative to the enemy's HP. When playing Skyrim, you should keep in mind the following: you get 1k HP, the enemy gets 1k HP as well.
