Doors Open and Close

"When one door closes, another opens." common saying

Do you believe that when one door closes, another opens?  It seems in my life I feel the need to completely close one door and honor what occurred during that phase in life, before another door can open for me.  Professionally, I have learned that in a few months the office I use will no longer be available.  So, what does that mean for me?  A consideration.  Do you consider options when one door closes?  What might it mean for your life?
