Time is beyond our control. It's the constant struggle of perception. Reflection may be seen , initially, as a waste of time. What's the point ofthinking about something that already happened ? Will it make any difference? When something happens we aknowledge it immediatly . But because sometimes "things" happen in such a small space of time we feel like mere spectators , watching without reaction somebody else's life. Reflection comes to claim those events and to provide them with meaning .To make them feel as part of your identity ( present ) and to reassure yourself that you are going in the right direction.
It's the comfortable illusion of control.
