In this brief video, Nadia Kalman demonstrates how three anti-social skills can improve the way you write fiction:

  1. Eavesdropping
  2. Pretending Imaginary People Are Real
  3. Muttering to Yourself

Although you need to have good social skills to manage your relationships and get on in life, you don’t actually need them to write good dialog. And dialog is what brings fiction to life.

She also talks about getting rid of unnecessary adverbs, using contractions, and writing short sentences. In other words, dialog needs to be credible.
