The ultimate goal of a habit-forming product is to solve the user's pain by creating an association so that the user identifies the company's product or service as the source of relief.

As fleeting commitments, diets often fail. Thinking of dietary choices as part of who you are...can give them real staying power

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

Many innovations fail because consumers irrationally overvalue the old while companies irrationally overvalue the new.

Users who continually find value in a product are more likely to tell their friends about it.

When designers intentionally trick users into inviting friends or blasting a message to their social networks, they may see some initial growth, but it comes at the expense of users' goodwill and trust. When people discover they've been duped, they vent their frustration and stop using the product.

The aim is to influence customers to use your product on their own, again and again without relying on overt calls to action such as ads or promotions.
