It is up to you to believe what messages you will receive and then determine how you will act upon those messages.
Some bias the message to only affirm their current beliefs and behaviors.
Others keep an open mind for the array of messages to be received and they think before they act next.
One is learning and applying what they are learning toward a goal or purpose as they take the words in, the other is not.
The messages are there for you to take in and process for what you will do with them.
“Words are only postage stamps delivering the object for you to unwrap.” — George Bernard Shaw —
