How to unlock the Introvert achievement in The Sims 4 - Definitive Guide
Start a game and pick an empty lot. Build a small room (4x4 I think it is) so there is room for a door to open and let the Sim in but not big enough to let the Sim lay down, using the square room tool in Build/Buy. Add a door and send your Sim into the room.
Select the sledgehammer from the Build Buy tool in the top middle of screen and remove the door.
Put the game on max speed until the Achievements pop.
This includes no computer chatting, no phone calling, and no talking to other sims.
This works best if you have a household with one sim.
Simply take care of the sim for the 24 hours while avoiding social actions.
Select New Game (Dismiss Tutorial if this comes up).
Scroll right and select 'Open the Gallery'.
Search for 'Basketcase Family +' and download the family made by 'Misier'.
Select 'Place Household' and choose Replace. After this go to the bottom right and press 'Play'.
Next choose 'Willow Creek' & then 'Streamlet Single'. Press confirm to load up the map.
Finally press the Ultra Speed button and the achievement should pop within a few minutes.
Also unlocks:
Should only take about 10 minutes.
Just make sure you don't interact with another SIM or do any computer socializing either.
The achievement will pop soon after. Credit to DARK X STEVE for the video

Full video guide:
It’s recommended you do this with a Sim that has the Loner trait. This will prevent them from making (or answering) any unwanted phone calls. If you have the Maid Service activated, you’ll need to do this on the weekend since the maid does not come by Saturday and Sunday (though it’s recommended you either fire your maid or don’t start this service until after you have the trophy). You also cannot go to work since you will automatically interact with your co-workers and/or customers.
If possible, free up about a 36-hour period just to give you some cushion for this. Go about your day as normal, but don’t do anything that may require social interaction. No computer, no phone, etc. You can eat, paint, play instruments, sleep… anything that is a solo activity.
Make it 24 hours without any contact with any Sim in any way shape or form to unlock the trophy.
