A while back I tweeted two simple sentences that popped into my head while I was scrambling eggs:
Know your limitations. Then shatter them.
Yes, that could easily have been one sentence, but the eggs told me to use a period instead of a comma for dramatic effect (see my post on commas). This morning I sat down with my cup of coffee and had every intention of writing the next scene in my fourth novel (which is a sequel to my first novel), then I opened the blinds and looked out the window and recalled those two sentences.
Can you really shatter your limitations?
