Hello friend @yusvelasquez.

As usual a great article that you share with us in this opportunity, I really enjoyed this reading and learning about the Pygmalion effect in our lives, where it is important to highlight what you express:

If the person believes that it is going to work, he/she keeps his/her positive expectations about what is going to happen and sticks to it until he/she gets what he/she is looking for. Interestingly, when the expectations come from the person to himself, it is known as the Galatea effect.

Great posts I could learn a lot from it, thanks for sharing it with all of us.
