English to Spanish Other Management

Estimados:

Junto con saludar, les agradecería ayudarme con la traducción de la idea, no me queda muy claro. A continuación les adjunto el párrafo en donde aparece:

To succeed at securing meetings using the phone, it really helps, if, deep down, you believe that it works. And if you were to watch and listen to most sellers doing half-hearted telephone prospecting, you could tell immediately that they, forgive the pun, are just phoning it in. Oh, they’re picking up the phone and dialing, but they’re just going through the motions. Their hearts aren’t in it, and frankly, neither are their minds. If asked confidentially, these sellers would admit that they don’t believe phoning prospects will create significant sales opportunities. This negative and flawed mindset becomes a self-fulfilling prophecy. Those who think they’ll fail succeed at failing.

Muchas gracias.
