Why does stopping a bad habit by willpower alone usually fail? Show answer

The habit meets a need. If nothing else meets that need, the trigger still arrives and the old behavior returns.

What are the three parts of a habit in Mel Robbins's model? Show answer

A trigger, a behavior and a reward. The reward releases dopamine, which locks in the loop.

What is Robbins's rule for breaking a bad habit? Show answer

Do not simply stop. Keep the trigger and the reward, and replace the behavior in between.

What did Robbins find was the real reward of her evening cocktail? Show answer

The ritual that signaled the workday was over. She kept the ritual with non-alcoholic drinks.

Why does Andrew Huberman intervene after the habit instead of before? Show answer

Many bad habits happen too quickly to notice in advance, so the usable moment is right after you catch yourself.

What is Huberman's protocol when you catch a bad habit? Show answer

Immediately do a different, easy, positive behavior, such as drinking water or a few minutes of breathing, every time.

What do Huberman's nicotine figures show? Show answer

Quitting cold turkey succeeds only about 5 percent of the time, and most relapse happens early, often in the first week.

How does Huberman suggest getting through the first week without nicotine? Show answer

Anticipate the times you used to use and fill them with exercise, cold exposure and positive social contact, with a physician's guidance on other aids.

What is Anna Lembke's reset, and what should people expect? Show answer

Thirty days without the substance or behavior. The first two weeks are usually hard, with improvement in weeks three and four.

What does Lembke put in place of the removed behavior? Show answer

Deep, honest human connection, telling the truth about everything, and doing meaningful work that is right in front of you.

What are Rangan Chatterjee's three steps? Show answer

Feel what you are feeling, ask how the habit feeds that feeling, and find another behavior that feeds it.

How can a replacement backfire? Show answer

If the substitute is itself intensely rewarding, it can become a new compulsion. Choose things like exercise, rituals and connection.

This is the short form. The full insight has every expert's reasoning, their own words and the sources.
