To pay attention means more than what people think it is.
Giving your attention to someone or something at a particular time for something in return.
It does not stop there, it requires you take into account details of what you are giving your full attention to.
Paying attention is a sacrifice because you leave every other thing to be with your focus at the time.
Paying attention is like giving cash in exchange for a commodity/services.
It means that you are giving something in exchange for another. Tradding
It is a price you have to pay (the cost) for something.
Attention is a commodity and same time the exchange.
Attention means you care, hence are committed to details.
Paying attention is giving back, it is love and it is sacrifice.
Next time pay close ATTENTION you never know what you might get in return or where it can take you.
Cheers.
