This is what you call "SELF LIMITING BELIEFS"

Belief systems are something that has been created in your childhood or while you were growing up.

It's basically what you believe in, especially what you think is possible and what you think is impossible.

Usually, belief systems are good, but certain beliefs can hamper your growth and progress.

For instance, if you are starting a project or you want to pursue something and you hear a voice from deep inside saying: "YOU CANnot do this" or "YOU are not worthy of this".... Then this is a limiting self-belief.
