“You suffer from the oldest delusion in politics. You think you can change the world by talking to a leader. Leaders are the effects, not the causes of changes.”

“It is not primarily as a religious leader that He is coming. You may look for Him rather as an educationalist in the widest sense of the word, advocating changes in our political, economic and social life.”

Benjamin Creme (1922–2016) artist, author, esotericist

“Let the world change you and you can change the world”

Ernesto Che Guevara (1928–1967) Argentine Marxist revolutionary

“That becomes the revolution, to be idealistic enough that you think you can change the world, and what you find is you can't change anything but yourself.”

“If you can change people's minds — you can change the world.”

Marina Abramović (1946) Yugoslav-American artist

“To lead in an ever-changing world, leaders must adapt and stay nimble.”

Indra Nooyi (1955) Indian-born, naturalized American, business executive

“Clarity is the antidote to anxiety, and therefore clarity is the preoccupation of the effective leader. If you do nothing else as a leader, be clear.”

“Whether you love or hate Ronald Reagan, he was a great leader. He really fundamentally changed America.”

David Cay Johnston (1948) Investigative journalist and author

“If you depend on the widespread lover's delusion, 'With my love he or she will change,' you have little chance to help yourself. This delusion is external control to the maximum. If things are not good from the beginning, they are very likely to change, but not for the better.”

William Glasser (1925–2013) American psychiatrist

“You must love those you lead before you can be an effective leader. You can certainly command without that sense of commitment, but you cannot lead without it.”
