The hallway of life and its many doors

I’m standing at the end of a hallway.  I look back.  I see it’s long.  So many doors that have been opened to or by me.  Amazing.  I’m not sure I realized this unless I’d taken this moment to look back.  They are all still open.  Interesting.  Yet, the side doors on the hallway are closed.  Closed for a reason.  Either chooses I didn’t make or lessons that I did learn.  The hallway looks clear and bright but I can’t always say that it was so.  It’s also straight but wait… I was certain there were twists and bends.  And I don’t see the stairs or incline I surely felt.
