““Remember and Share - For some businesses, forming habits is a critical component to success, but not every business requires habitual user engagement. - When successful, forming strong user habits can have several business benefits including: higher customer lifetime value, greater pricing flexibility, supercharged growth, and a sharper competitive edge. - Habits can not form outside the “Habit Zone,” where the behavior occurs with enough frequency and perceived utility. - Habit-forming products often start as nice-to-haves (vitamins) but once the habit is formed, they become must-haves (painkillers). - Habit-forming products alleviate users’ pain by relieving a pronounced itch. - Designing habit-forming products is a form of manipulation. Product builders would benefit from a bit of introspection before attempting to hook users to make sure they are building healthy habits, not unhealthy addictions (more to come on this topic in chapter eight).””
