"Faced with the choice between changing one's mind and proving that there is no need to do so, almost everyone gets busy on the proof"

John Kenneth Galbraith's quote speaks to the human propensity to avoid change and cling to the status quo. He recommends that when faced with the choice between changing one's mind and proving that there is no need to do so, many people will choose the latter. This is because it is easier to remain in our convenience zone and prevent the discomfort of modification. We typically discover it simpler to justify our present beliefs and actions than to challenge them and think about options. Galbraith's quote highlights the value of being open to change and being willing to challenge our own beliefs and actions. It is only through this procedure of self-reflection and development that we can truly progress and reach our complete capacity.
