“Not writing is probably the most exhausting profession I’ve ever encountered. It’s very psychically wearing not to write – I mean if you’re supposed to be writing.” – Fran Lebowitz
Sometimes you reach a point where your batteries are dead. No matter how long you sit in front of that blank screen the words elude you.
When that happens it’s not the time to quit but it may be time for a break to recharge. Some people call it filling the well.
Go read something, watch a movie, tour an art gallery, take some photos, listen to music, and go out for something to eat. Use your senses and re-charge your batteries. Then plant your butt and write.
