PrinceAdepoju: 4. "Description begins in the writer's imagination, but should finish in the reader's."
― Stephen King
For a piece of writing to qualify as readable, it needs to posses this basic quality - a good piece of writing has got to beengaging. Leaving the reader spellbound and fascinated can be a bonus, but before it comes to that, it simply needs to hold the reader's attention. And when we mention attention, it is assumed that the attention is positive.

The web of words is spun in the writer's mind, but it needs to be effective (and engaging) enough to trap the reader ever so subtly that it goes unnoticed. Within a heartbeat, the reader is enslaved. In a good way, of course.

5. "Easy reading is damn hard writing."
― Nathaniel Hawthorne
Isn't it ironic? Writers may often make the mistake of going that extra mile to ensure that their writing sounds highbrow and esoteric. Recondite, even. With their noses in the thesaurus, they bend backwards to make it abstruse and perplexing. Are you a little confused as to where this is going?
Well, the point that's being made here is that complex words don't make a good writer, enjoyable writing does. Also, entwined plot lines have the potential to be interesting, only if they aren't muddled up in confusion. As an aspiring or an introspective writer, you need to double your efforts not to complicate things but to simplify them.

That's right
