For a year I kept three books open on my nightstand. I finished none of them. When I returned to single-book reading, completion rates doubled and retention improved noticeably.

Parallel reading feels efficient. It mirrors how we consume feeds — a little of everything, depth nowhere. But books reward sustained attention. Characters need continuity. Arguments need accumulation. A paragraph on page two hundred only lands if you remember the setup on page forty.

My rule now is simple: one book until the last page, then a day of rest, then the next. The rest day matters. It lets the book settle into memory before something new arrives.

If you write as well as read, the benefit compounds. Sentences from a finished book echo in your drafts. You absorb rhythm, not just information. That transfer rarely happens when you abandon books halfway.
