Customers should Relate to Your Product & Be Open to Change
Your target audience should share your definition of the desire that your product solves, and be open to change.
The next step of effective marketing is based on the simple fact that you can't please everyone, because different people want different things.
Indeed, even when some people seem to have the same desire, they often define it in different ways.
For instance, to some, adventure means thrill-seeking.
To others, it means international travel.
