We all need daily reminders of who we are and where we've been -- without that point of reference, we couldn't possibly know how far along we've come. One way to remind us are photographs, which we often take for granted. Not necessarily because one person can "afford" them and another cannot, nor because we have such great access to them.
Photographs are like frozen moments in time that don't change unless we change -- maybe in our look or how we view them. Portraits, are mirror images that don't disappear.
