Professional success certainly requires hard work, through which we sometimes cease to derive pleasure from life. Such a disturbance of the boundaries between work and private life can lead to fatigue, health and family problems, as well as to burnout. From a purely business point of view, it is not profitable at all. Without charging the battery, you cannot operate effectively in the long-term perspective. This is why it is so important to find a balance between all areas of life: work, family, and leisure. You need to pursue efficient time management, knowing what actions bring the best results and what you should eliminate. Psychology comes in handy here, as it, on the basis of extensive research, explains why some people cope effectively with tasks in a given time and achieve success regardless of how it is defined, and others do not.
