Give birth to a thought that preempts all other thoughts. The goal is to achieve nirvana.
An incomplete nirvana to be sure, but a form of immediate or instant gratification. In marketing terms, this instant gratification impulse, or thought, is the goal.
By making the reader/viewer stop on a dime and buy your product or service.
Doing a good job, a fantastic job, of marketing to the nirvanic impulse means being totally honest and transparent about that which you are selling. The transparency of your efforts must be completely honest. You must completely believe in the product through experience, otherwise the viewer will instantly see through the effort and click away.
