Before we get into the guide, I want to recommend the most comprehensive guide on how to change your habits and get 1% better every day: new book Atomic Habits. 

Packed with evidence-based self-improvement strategies, Atomic Habits will teach you how to make the small changes that will transform your habits and deliver remarkable results. 

Atomic Habits will reshape the way you think about progress and success and give you the tools and strategies you need to transform your habits—whether you are a team looking to win a championship, an organization hoping to redefine an industry, or simply an individual who wishes to quit smoking, lose weight, reduce stress and achieve success that lasts.
