People who read a lot are rarely more disciplined than people who do not. They have usually just removed more friction.
The single most common reason people stop reading is that they are stuck in a book they are not enjoying and feel obliged to finish. Abandoning it is not failure. A book you never open again costs you every evening it sits there.
Most people have far more small pockets of time than long quiet evenings — a queue, a commute, ten minutes before sleep. Books are usually lost to the fact that starting feels like it requires a proper session. It does not, if picking up costs nothing.
This is the practical case for reading on a phone: it is the device you already have. Wordema keeps your place in every book automatically, so opening it costs one tap and you are back exactly where you stopped.
Momentum matters more than ambition. Finishing three short books does more for a reading habit than not finishing one long one. Short classics and easy reads are good places to begin.
If you drift off, re-read the same line, or surface from a page with no memory of it, that is usually a navigation problem rather than a comprehension one. RSVP removes the navigation by holding every word in one place. How it works.
