What time of the day is best for your creativity or active process?
I tend to siesta in the afternoon. Most creative times tend to be early or late (when interruptions are at their lowest).
If I am in serious coding mode I’ll often be most productive between about 9pm and 1am.
And pure creativity can happen any time, and is often strongly influenced by diverse and changing surroundings. I often record my most creative stuff while driving or cycling, or it just comes out in debate with someone else.
