Hypothetically how would this look if you were designing Facebook for the first time ?
Samuel Legge

He/she will join/access Facebook (action), if he/she feels need for socialization (trigger), because he/she needs to be socially accepted (frustration).

“Every behavior is driven by one of the three core motivators: Seeking Pleasure and Avoid Pain; Seeking Hope and Avoiding Fear; Seeking Social Acceptance and fearing Social Rejection.”

Once you are aware what the internal trigger (core motivator) is, you start using external triggers to bring users back to your product and use it — “Wish your friends happy birthday”, “Share how do you feel”, etc.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
