What Is a Hook?

Habits by definition are simply impulses to do a behavior with little or no conscious thought. Half of what you do every single day, whether you like it or not, is done out of habit. I believe that we can use these habits for good and change people's lives through the very products they're building. We all use products for one reason and one reason only: to modulate our moods. And so that's why I do what I do. I don't teach this stuff to the gaming companies and Facebook and Google. They already know these techniques. I'm here to teach everybody else the same underlying psychology so that you can change your customer's habits for good.
