Very sleepy. Started writing past midnight, and only managed some 1,600 words or so. Drawing a thousand words from the word bank to make the quote. Good thing I was prolific yesterday. The ease of writing today was about a 4 out of 10.
One thing is becoming clear: I need high levels of energy and optimal physical health in order to maintain mental clarity and enthusiasm. I think this challenge is going to revolve as much around physical well being as it is willpower and creativity.
