I do my best thinking at night, right before I fall asleep. And again first thing in the morning, as I'm waking up.
For me, my bed is a place where my mind is running and ideas are swirling. It's a constant reminder of what I have to do, when I have to do it, and how I want it done. It's my favorite thought-process-time-of-day. It's where ideas are born; my ideas. It's where I get my inspiration. And it is there... where I close my eyes and dream.
