well i think it just deppends on what you do for a living ... i mean , yes bussiness mans make the most of the morning because they can do more of their tasks find out better places to meet with potencial clients and stuff ...
but lets take a bussiness owner like an example ... if he owns a nightclub , theres no point in wasting energy into been awake just because its early
personaly i found the night a better time to find inspiration into my proyects there is an study that talks about how in the night people are more sincere and creative

so my point is it depends on people

well thats my point of view i hope it not disgust you , here its night now btw hahahaha ;)
