It remains a challenge to explain how individuals transition from one goal cycle to the other . But this is a relevant question in lifespan development. Life course theory conceptualizes series of events respectively transitions in life . While there are many terms to describe life transitions (e.g., turning points, momentous events, etc.), there seems to be agreement that transitions are about major life changes .
Life changes can be school transitions, life events such as parenthood, migration , or retirement . These normative events mostly are experienced positively; there are also unexpected and involuntary events that are perceived more negatively though . In other words, transitional phases potentially present opportunities and uncertainties . It is difficult to disengage from prior goals and commit to new ones, as goals stand for a hoped future and consequently also support psychological well-being . Cultural and societal changes can trigger change, but there is also increasing variability in developmental journeys within societies and generations as people exercise agency, i.e., taking conscious decisions to initiate and go through life course transitions, be it as an adjustment to the current social environment or not .
Learning helps to cope with stress from life transitions  while going through transitions conceptualized as experiencing disequilibrium and stability adds to psychological resilience . Seen it that way, transitions naturally involve chance, choice, and change, all interlinked to trigger, enable, and result in personal development and growth.
