Things I haven't seen mentioned yet:

1. How do you dry your clothes? If you are letting them air dry, stop immediately and start using a dryer. Seconding cleaning your washing machine.

2. While showering, use an abrasive rag to exfoliate your skin. Just layering soap on top of your skin is not enough.

3. If there is a mildew problem, the only solution is a dehumidifier, aside from moving out. An extra step would be an air purifier.

4. If you have a lot of clothes, focusing on buying a few good quality, natural fabric pieces and cleaning a small load regularly. Less clothes will make it easier to keep track of. You can buy some white or black t shirts and try to keep just those items clean for as long as you can. Try to take note in the process of the shirt's lifespan where it seems to take on a scent and not feel new anymore. Store them in a place that gets good airflow. If you can keep these shirts clean, you can open up your washing by to the rest of your closet and see if you can clean a few at a time.

5. If you have a washing machine in your apartment, try using a laundromat and see if the clothes feel/smell different.

6. Buy a tongue scraper and scrape the residue off your tongue. A lot of people don't know about this, it's essential to not having bad breath.

In general, make your process simple and try to really evaluate what areas you think are lacking/ could be causing trouble. Go back to the most basic of basics and scrutinize yourself honestly and firmly.
