have you ever tried this?
i read an article awhile back written by a psychologist talking about the brain. a small protion of this article mentioned making a deal with your brain to better focus or to help those who have trouble sleeping.
if you ever find your mind racing, or in and endless chain of thought, and it is hindering your ability to do something you may want to give this a try. you can actually tell your brain “ok, i promise i will think about all of this later tonight or tomorrow”. i thought this was a load of crap when i first heard it. i have actually tried it a few times recently when i can’t fall asleep because i am thinking too much. it actually works!!
so if you find yourself in a situation mentioned above try making a deal with your subconscious. you will be surprised at how well it works, or maybe i’m crazy.
