User habits are a competitive advantage. Products that change customer routines are less susceptible to attacks from other companies.

Companies leverage two basic pulleys of human behavior to increase the likelihood of an action occuring: the ease of performing an action and the psychological motivation to do it.

Habit-forming products often start as nice-to-haves, but once the habit is formed, they become must-haves.

Instead of relying on expensive marketing, habit-forming companies link their services to the users' daily routines and emotions.

Reducing the thinking required to take the next action increases the likelihood of the desired behavior occurring unconsciously.

For an infrequent action to become a habit, the user must perceive a high degree of utility, either from gaining pleasure or avoiding pain.

To initiate (user) action, doing must be easier than thinking.
