Step 1 of 5 · External Trigger
External triggers are a bridge to internal triggers, not a permanent engagement engine.
Misconception
That more notifications, emails, and badges automatically drive more usage.
Reality
Paid and earned triggers only buy the first few cycles; the goal is to migrate users toward owned and internal triggers, because a product that must keep prompting has failed to form a habit.

Step 2 of 5 · Internal Trigger
Internal triggers are pre-existing emotions you associate with, not features you design.
Misconception
That internal triggers are something you build into the product through clever features.
Reality
Internal triggers already exist in the user's mind as itches like boredom, loneliness, or uncertainty; your job is to attach your product to an existing emotion, not to manufacture a new one.

Step 3 of 5 · Motivation
Motivation and ability trade off — low ability can be rescued by high motivation and vice versa.
Misconception
That you can substantially raise a user's motivation with better copy, incentives, or hype.
Reality
Motivation is far harder and slower to increase than ability; when a user won't act, it is usually cheaper and more effective to make the action easier than to try to make them want it more.

Step 4 of 5 · Ability
Simplicity is a function of the user's scarcest resource in a given moment, not a universal metric.
Misconception
That simplicity means fewer features or a cleaner interface.
Reality
Ability is about lowering the cost of the target action along whichever of the six dimensions is scarcest for that user — sometimes the bottleneck is brain cycles, sometimes social deviance, and the fix is context-specific, not aesthetic.

Step 5 of 5 · Action
B=MAT: behavior requires trigger, motivation, and ability at the same moment.
Misconception
That if users are motivated enough, they'll push through a difficult action.
Reality
Behavior only occurs when trigger, motivation, and ability all coincide simultaneously; a missing or weak factor kills the action even when the other two are strong, so you must diagnose which one is absent.
