It's always necessary to know when a stage of one's life has ended. If you stubbornly cling to it after the need has passed, you lose the joy and meaning of the rest. And you risk being shaken to your senses by God.

The ambitious will always be first in the crowd; he presseth forward, he looketh not behind him. More anguish is it to his mind to see one before him, than joy to leave thousands at a distance
