Being tired can really impact your creativity. I find that you tend to run out of ideas and things to post about. Maybe getting out and about can help fire up the imagination. Much of what I blog is based upon things I hear and experience in life. Maybe I should do a little media-centric posts featuring stuff I see on TV and music I listen to, but I do some of that already. Creativity relies upon being open to expressing ones self in different ways and experiencing new things. Maybe I just need more sleep and to stop overthinking things like I do.
