Let's make this easy to understand. Are you married? If so, that is a base example of how we are all sales people. You managed to convince someone that out of all of the other possible choices in the world, you were the one they should commit to spending the rest of their life living with. We don't give ourselves enough credit here. Pausing to think about it, that's an incredible accomplishment from a sales perspective! However, it didn't happen overnight did it? In most cases no. Often this arrangement takes place over months if not years, and it's generally considered very risky for a marriage to take place too soon.
