There’s immense power in self-belief; people often do not believe in themselves, and they believe in what others say. Others say such things because they have a limited mindset, or they do not want those people to grow. If you believe in something that will work, see if it works, and if it does work, there’s no looking back. You move as if no one is there, listen to no one, see no one, and you will find success surely.
