NaNo is more akin to a marathon than a sprint. To keep the stamina to last us through the entire month: it is important to take care of ourselves and relax when we need it. Get yourself that nice cup of tea, sit down in the fresh autumn air for a moment and take in the moment. Breathe! Take a moment and gather fresh energies.
Keep writing your story. One word and one day at the time. These storms will pass and the way out is through!
