Studying history is observing the changes that human kind went through and understand our behaviour today. The process of people development, mentoring, training and coaching aim at helping a person change their behaviour and act in a different way. In order to make progress we need to understand where we stand today and what has shaped our behaviour until today; how we have behaved in similar situations; how we formed our current beliefs; what we have achieved in the past. It is our personal history that evolves within the historical framework where we are born.
