Only if I read at least 50% of it. Otherwise no.

For some people it’s definitely a case of not finding the right book. For others they genuinely do not enjoy reading.

I don’t like to presume either way.

Read a little bit each day even if you have to force yourself. Not a lot. Just a few minutes or a chapter. Go through and pick something that stands out to you.

Also join reddit communities like r/lightnovels or r/manga where people who enjoy those books are discussing them and looking for recommendations.

If you’re going to be on Youtube anyway why not look up book/manga/light novel reviews or podcasts?

Being around people who enjoy the same things you do will help give you motivation to read again and confidence that you aren’t alone enjoying it.
