Sleepless night? Tried to go to bed at half-past three in the morning but failed to do so? Tossed and turned? Felt like your brain was about to explode with all that thinking? Watched the walls of your room get brighter with the rising sun?
Crawl out of bed and write! I will reach seven thousand words tonight! Well, this morning, actually. Seeing that it's half five and all. Damn birds won't shut up.
