Regardless of whether you’re a plotter or pantser, you might come to a place mid-way through where your story feels like it’s gone off the rails. During NaNoWriMo, the mantra is just plow through! Keep writing! It’ll work itself out! But I think better advice is to check in with your basic story beats. It doesn’t matter if you plan them ahead of time or figure them out partway through writing. The important thing to know is that these beats are an extremely useful tool to avoid writer’s block, mushy middle syndrome and general NaNoWriMo fatigue.
