Famous quotes containing the word marker:
“Personal change, growth, development, identity formationthese tasks that once were thought to belong to childhood and adolescence alone now are recognized as part of adult life as well. Gone is the belief that adulthood is, or ought to be, a time of internal peace and comfort, that growing pains belong only to the young; gone the belief that these are marker eventsa job, a mate, a childthrough which we will pass into a life of relative ease.”
