How do I break a bad habit?
Epictetus

Every habit and every faculty is kept and increased by its own corresponding acts: walking by walking, running by running. Your habit is a fire; every repetition is wood on it. So first, stop feeding it. Do not say, I will be moderate tomorrow. Set another act in its place today.
