how ads persuade you (4 steps to how they tap our psyche)

There is a method to how ads persuade you...Even when we know we should stop something, why do we continue to keep wanting it for a while. Why does it feel weird to stop doing something, or drinking alcohol for that matter, while everyone else is drinking?
I go into how how ads persuade you (and me) and how they basically tap our psyche to keep wanting more of what we (maybe) know we shouldn't have. There's a real science behind this, and when we become a bit more aware of it, suddenly we start to recognize how influenced we might be.
