According to my dad, it is INCREDIBLY IMPORTANT to remember the events and relationships of your life.  In Biblical times, people were instructed to build altars so that they and generations to come would remember significant moments when God met their needs.  Today, this can be done by simply snapping photos with your phone and sharing them via social media.  The important thing is that we remember, so that we can keep our compasses pointing in the right direction and help others along the way.
