Find the internal trigger that would cause a user to use your product or service.

An internal trigger is a kind of trigger inside us that converts a certain feeling or emotional state into an action. As an example, let’s take an Instagram user: when the user sees something beautiful, they automatically get their phone and publish a photo. One of the triggers that we can observe here is the fear of missing out—if that user does not publish the photo right away, it might be gone forever.

To make your product addictive, you must understand deeply the emotions and feelings that can be strong internal triggers.

1. First, identify particular frustrations or pain points in emotional terms, rather than product features.
   You can do this by studying products that are successful in forming habits. Don’t copy them, but understand the mechanics.

2. One of the best methods for finding the trigger is to ask five whys.
   This popular exercise was first adopted in the Toyota manufacturing process. It will help you find particular emotions, for example, the fear of missing out.

3. Finish this brief narrative using the most frequent internal trigger and the habit you are designing: “Every time the user (internal trigger), they (first action of intended habit).”
