How much should I plan ahead for a novel?

Webnovel

Plan the first arc, maybe the last one, and you can pants the rest in between. Webnovels require pumping stuff out fast and delivering genre goods more than worrying about quality or artistry.

I only keep an idea for the next arc, the rest I let my writers instincts dictate. If I kept with the plan my story would be vastly different and way more mediocre. If your instincts are telling you do something different, listen to it.
