Holding on to the Dream

Even though I am pushing 40, I still have this dream of what I want when I grow up.  With each passing day, my brain tells me to let the dream go.  It tells me to face this reality I am living in; accept where I am and what I got.  But my heart won't let go, no matter how hard I try I can't make it stop.  So, I keep holding on. . . Because I'm thinking if God keeps it in my heart, then maybe just maybe it's in my future, too.
