Well, widen your horizon then, read something completely different. Alternate history, real history, a classic or 2, hard science (without the fiction part), some philosophy, etc. I tend to move from genre to genre to avoid getting stuck in a rut, something I started doing when in primary school after having read half a bookshelf of adventure/western style books and getting thoroughly fed up with the genre...

The same advice applies to screens as well. Lots more than Netflix out there.

That's a good point. It's easy to 'never run out of books'. It's quite easy to 'run out of books in the particular category I like'.

If anybody has recommendations for books like Zombie (fiction) or Children of Time (a novel told in part from the perspective of an advanced, non-human society), I'd be very happy to hear them.
