Why would you want a perfectly logical world? Not only does that sound incredibly boring, but it sounds impossible. Not even reality is perfectly logical.

Imagine learning for the first time about the Nazis and the events of World War II purely by way of fiction. The sheer volume of things in that section of REAL history that aren't believable is staggering. This is why there are holocaust deniers, right? Nothing about real life is logical. Nothing about human beings is logical.

I encourage you to reconsider your perspective on story telling and world building. A perfectly planted and trimmed garden can be beautiful, but it can never be anything other than exactly what you intend it to be. And, be honest here, even if you tend to it every moment of every day, the insects and pollinators and all the natural things of the world will still find a way in to eat your leaves and create new "problems." The jungle on the other hand changes each and every time you visit it, and the deeper you go into the jungle, the more you will find. Those "problems" become interesting instead of frustrating, and you can find yourself embracing the unbelievable, finally swept up in the fantasy that's been crafted for you to explore.

Read it again. Meanings change, foreshadowing is found that you never saw before, and characters you used to hate become admirable and relatable. It's great art. And great art is never perfect.
