Enjoy your possessions, but be cautious as to how much you allow them to define you.  Appreciate your photos and mementos, but be aware if they are holding you in the past.  What is the spiritual path about?  About releasing your identification with the ego.  Why?  So as to know the meaning of oneness and its resultant loving kindness and peace.  If you can do this whilst still enjoying your possessions and memories, realizing that no-thing you have is really “yours,” then “have” at it, Love.
