Scott Allan's book "Do the Hard Things First: How to Win Over Procrastination and Master the Habit of Doing Difficult Work," which provides a comprehensive guide to overcoming procrastination. The book examines the psychological roots of procrastination, exploring the fear of commitment, fear of the unknown, fear of discomfort, fear of decision-making, and fear of criticism as primary motivators for delaying important tasks. The author also presents a practical system for building better habits and managing procrastination, including strategies for taking ownership of behavior change, building a list of "things-to-get-done," time-blocking tasks, and implementing the 80/20 rule. He emphasizes the importance of recognizing and challenging limiting self-talk, creating a positive environment, and employing the Premack principle and temptation bundling to reinforce desired behaviors. In addition, the book offers advice on managing distractions, identifying and overcoming constraints, and establishing a consistent review process to maintain momentum and achieve long-term goals.
