Creative Rut or Artistic Breakthrough

So apparently when you are in a creative rut your actually about to have a breakthrough. If this is true someone tell my brain ASAP! So according to Alan Lightman getting stuck is a great thing, it lets your mind go through all these ideas and think out of the box. I personally don't like being in a creative rut and I find it exhausting and a pain in the ass but according to science it is good to go into a rut, so I guess we should listen to it. Lightman also says that you should work towards your inspiration instead of waiting for it to hit you, now this is something I can vouch for. After hours of working on something and getting no where then you get hit with this rush of ideas and insiration is the best thing.
