There's a mod to fix that. It's called the unofficial brain patch.

Always Argonian

Always some kind of warrior

Always does the golden claw

Greetings Marsh-friend.

No, it was once

I always play as a female
Always hoard alchemy ingredients, even if I don't use alchemy
Always take perks in sneak and archery for sneak attacks
Always side with the Greybeards
Always sheathe my weapons when I'm in a city or village
Always fus-ro-dah Nazeem
Always take a follower (always Kharjo or Jenassa)
Always do Amren's quest in Whiterun
Always get the dragonstone before talking to Farengar

• Always play as a female
• Always collect alchemical ingredients and brew potions, even if you don't perk the Alchemy skill
• Never walk down the middle of a passage, that's where the pressure plates are usually located.
• Never stand directly in front of a treasure chest when you open it, that's usually the targeted area for traps.
• Double check your spells, active power/shout, and apparel before entering melee so there are no surprises when you arm yourself. I hate arming only to see dual healing spells at the ready.
• Don't be shy about running away to survive (I used to fight to the death rather than retreat).
• Drink the appropriate potions to pump up your health/magicka/stamina/insert_fortify_skill_here before entering melee.
• Poison melee weapons.
• Optionally: save so you don't have to do this all over.

It's hard. It took me a long time to break the habit, but I'm finally at the point where my non-alchemists don't try to get every ingredient in sight. It still takes me a few minutes at the beginning of a new character to remember to gather them or not, but then I'm fine.

As for things I always do...

These days all of my characters use a conjurable horse mod even if they don't otherwise use magic.

I use My Home is Your Home, but I never have more people than beds in the house.

I always organize my items, clothing, etc when I move into a house.

All of my characters cook and bake. Since Heathfire, I won't live in a house without an oven, even if I have to use the console to put one in.

Always eat, sleep and bathe.

Always do at least Dragon RIsing, even for my non-DB characters, because I like having dragons in the game.

Always play female.

Always play mage.

Always play pick nirnroot.
Always clear the forts before the Civil War quests.
