I do my best writing when I am relaxed and have some good music playing. Haven't been able to relax enough in about a year,as I've had a child and have a million things to do besides. Lol. But I will be attempting it. Soon. surprised
Regrettably, I, too, write at best by nightfall. I only say regrettably because I adore sleep as much as I do writing 8D
A nice, classical composition is ideal for writing in my case, as well as having a decent theme in mind.
