" A chef wields dozens of tools, from spatulas to potato scrubbing gloves. Every once in a while, he’ll need the pastry brush, but every day he’ll use a chef’s knife, a frying pan, salt, and a stove. Like a chef, a motivation hacker has a core set of tools. I’ll introduce these in Chapters 3 and 4: success spirals, precommitment, and burnt ships. Sometimes you can reach into your motivation pantry (Chapter 12) and pull out some timeboxing, but it’s often best not to get too fancy. And just as the chef who dogmatically used his chef’s knife for everything would cook a terrible pancake, so would a motivation hacker fail to quit an internet addiction using only precommitment. No single technique can solve every problem. This book will recommend several approaches to increasing motivation. Use more than one at a time. "
