The 2nd law (Craving): Make it attractive

A habit is a behavior that has been repeated enough times to become automatic. The ultimate purpose of habits is to solve the problems of life with as little energy and effort as possible. Any habit can be broken down into a feedback loop that involves four steps: cue, craving, response, and reward. The Four Laws of Behavior Change are a simple set of rules we can use to build better habits. They are (1) make it obvious, (2) make it attractive, (3) make it easy, and (4) make it satisfying
The process of building a habit can be divided into four simple steps: cue, craving, response, and reward.* Breaking it down into these fundamental parts can help us understand what a habit is, how it works, and how to improve it.In summary, the cue triggers a craving, which motivates a response, which provides a reward, which satisfies the craving and, ultimately, becomes associated with the cue. Together, these four steps form a neurological feedback loop—cue, craving, response, reward; cue, craving, response, reward—that ultimately allows you to create automatic habits. This cycle is known as the habit loop
The 1st law (Cue): Make it obvious.
The 2nd law (Craving): Make it attractive.
The 3rd law (Response): Make it easy.
The 4th law (Reward): Make it satisfying.

We can invert these laws to learn how to break a bad habit.
Inversion of the 1st law (Cue): Make it invisible.
Inversion of the 2nd law (Craving): Make it unattractive.
Inversion of the 3rd law (Response): Make it difficult.
Inversion of the 4th law (Reward): Make it unsatisfying.
Problem phase
Cue: Your phone buzzes with a new text message.
Craving: You want to learn the contents of the message.
Solution phase
Response: You grab your phone and read the text.
Reward: You satisfy your craving to read the message. Grabbing your phone becomes associated with your phone buzzing.
