Mental exhaustion is not just about being tired or demotivated above average. In the case of a mentally exhausted person, as well as in a burned-out person, short rest does not restore strength. Former hobbies or work are no longer enjoyable. Everything seems too much and one just doesn’t have the time to deal with it. The rhythm of life of a mentally exhausted person is no longer sustainable in its current form, and major or minor changes are needed to feel better.
