I realize I might be a relatively fast reader, and this fast reading I only did in English (while my mother tongue is Dutch), but do not underestimate how quick some people can read?
I suppose I can concur in your 'low complexity' argument: I did not read Tolkien in my teens, and probably would have skipped all the poetry while reading.
Edit: Clarification: 15 books each weekend should be read as ==>> I traded my 15 books for 15 new books each weekend, reading them during the weekend and when not in school
So you mean 15 books each week, not each weekend! I was surprised when I read that, but this makes more sense.
So my advice would be to get in the habit of reading, but be mindful of the details of the habit you are establishing.
Honestly, its not a target it is just what happens when you read a lot - you get through books.
As for YouTube or Netflix, I dont really watch that much and can't really understand how people spend that much time on them. Given that though, I read instead and lots of people dont understand that. Each to their own, happiness is different for everyone etc
not Having Netflix is a start. Realizing that most Netflix shows gets dumped mid-story after 1 or 2 seasons and will leave me without closure is another
