Need vs. Want
I need to eat dinner tonight.
I want to dine at a fancy restaurant, and enjoy a fine bottle of wine.
I need to have a job, to pay my bills.
I want a career.
I need a way to get to and from work each day.
I want an SUV with leather seats and a sunroof to make that trip more enjoyable.
Three pairs, each essentially describing the same thing. But while the “need” is relatively basic, the “want” adds a flavor of preference and desire. The gap is good marketing.
Even better marketing is when you convince your customer or audience that they want something so much, that they actually need it.
I need a new BluRay DVD player.
I need a vacation to Hawaii.
