I read 4 books at once

I can explain why. But first, some background.

My husband is satisfied if he can read a book in a month. I read several books at a time. He discovered my seemingly chaotic way of reading, which naturally led him to wonder:
“Why do you do this? Wouldn’t focusing on one book at a time be better?”

No. You see, all the books have their function.

Here are the 4 different settings for which I need different books:

1. The main book

This is the book I read when I go to bed at night, drink my morning coffee, and find time to read during the day.

2. The audio book

I always have to have an audiobook available. I listen to this when I drive alone, do housework, and go for walks. I love to shut out the world when life is hectic. Noise-canceling headphones🙌

3. The getting back to sleep-book

This is a book I read when I wake up at night and can’t get back to sleep. Often I choose a Sci-Fi book. I need a book that is a bit technical and seemingly endless, so it can quiet my mind and promotes sleep.

4. The sauna book

We have a sauna. 🤩 Sitting in the sauna and reading is my favorite relaxation.

The book I take with me to the sauna gets destroyed. The glue that holds the book together dissolves, and it becomes full of sweat. I have to buy two copies of the sauna book since I want a copy for the bookshelf.

What about you? Do you also read several books at the same time, or do you focus on one at a time?
