"Holes" in Hygiene
Every imperfect creature is going to have Contradictions, Naivety, and or Hypocrisy at points in time or in areas of their life, and some of that could be life-long.
The holes are normal.
That does not mean that you are a failure or that you should discard and commit any less to what you have learned and gotten under your control.
You can't do everything right.
So just do what you can.
And aim to do more/better over time.
Sometimes you don't need to learn new things, but rather how to do old things more efficiently, and to greater degrees.
Keep on pushing and growing on your hygiene journey.
