Writing is not always borne out of inspiration that strikes you like a lightning bolt.
Many days, writing will feel like a chore.
Drudgery.
As with everything, you will have good days and bad days. Some may figure out the pattern, most will not.
But one thing I know for certain is this: I would not be a writer, if I did not drag my ass through the uninspired days, so I could find my voice.
