There is nothing beyond your reach if you have self belief and confidence in place. Even if others do not invest their belief in you, you should be sure of yourself. Belief is infectious. You believe, and the world follows.
Vikram Gandhi, a filmmaker, tested his own beliefs and those of people around him in a social experiment wherein he posed as a guru, Kumare, and made a whole sect follow him, believe every word he said. As you’d see in the video below, he compelled people to follow a religion he created. All it took him to cast his influence on people was his belief in himself.
Vikram Gandhi made a film about his experiment, ‘Kumare’. It received widespread acclaim by critics. About his experiment, Gandhi said, “the biggest lie I ever told and the greatest truth I’ve ever known.”
