You have to challenge your considerations and go as far as possible. Just by expressing that a particular idea isn’t correct, isn’t sufficient.
Your cerebrum is sufficiently shrewd to understand that you are opposing an idea without a genuine explanation.
Challenge them by coherent and target outlooks. So for instance, if your idea is: “I am useless.” Continue by asking: “For what reason am I useless.”
An explanation will spring up and you have to challenge that reason once more.
Shouldn’t something be said about all the individuals that would state that I truly offered some incentive for them? Etc.
