In popular psychology, a quarter-life crisis is a crisis "involving anxiety over the direction and quality of one's life" which is most commonly experienced in a period ranging from a person's twenties up to their mid-thirties[1][2] (although it can begin as early as 18).[3] It is defined by clinical psychologist Alex Fowke as “a period of insecurity, doubt and disappointment surrounding your career, relationships and financial situation".[3]
