Don't Think About Elephants

My hip-hop remake of the song "Don't Think About Elephants" from the Inception soundtrack. The song plays during the rotating hallway scene of "Inception"

Tell me your writing troubles.

For me, it's dialogue and my mind going blank. At times, my dialogue feels real, and at others it feels too forced, or my characters lose their voices along the way. Usually I can hear a character speak in my head (no I'm not crazy). But sometimes my characters sound the same. I've been developing them for about 17 months so I know my characters all too well. I also have trouble with coming up with new plot, since I am more of a discovery writer than anything. I have outlines planned out, but I usually won't follow them like a map. Tell me some of your writing troubles.
