Forty years ago, an experiment began at Stanford with a group of four-year-olds, which convincingly proved that the ability (or inability) to sacrifice immediate benefits and wait for greater rewards determines no less than our entire destiny. Each of the children was offered a piece of marmalade and promised to give a second one if the baby waited a quarter of an hour and did not eat the treat. It would seem like nothing particularly serious? But all the patient kids achieved success when they became adults, but the hurry-ups did not. This book is about why it was so important not to eat the marmalade right away. About what decisions and actions today we can provide ourselves with serious bonuses in the future - or guarantee their absence. We published it for everyone who cares about success, self-realization and happiness - their own and their children.
