This book is for all those who find it difficult to motivate themselves and feel fatigue or weariness in the context of their work that is not only physical. Stress, emotional hyper-investment, anger, annoyance, anxiety cause a strong loss of energy which reduces well-being and performance and can lead, in chronic cases, to burnout. Fortunately, it is reversible. Through a better understanding of the functioning of the brain, Bertrand Canavy invites you to replenish your energy intake by reorganizing your daily activities in order to increase the sources of pleasure and limit the areas of loss of mental energy.
