If you suspect that you might be a writer, then there is one thing you must do.
WRITE.
Grab a notepad, a laptop or the back of that shopping list stuffed down the bottom of your handbag. Unless she is given a voice that frustrated writer trapped inside you will drive you (and everyone around you) crazy.
Figure out what is stopping you and find a way past it.
Heed this warning from Frank Kafka:
"A non-writing writer is a monster courting insanity."
