Thoughts on the restless mind (a.k.a “monkey mind” ), exhaustion from over-thinking, and simple breathing exercise to help drop the bananas, here in this article on Zentacles.
“You’ve got a monkey in your brain. Let’s call him Alan.
Alan is like most normal monkeys. He swings about from tree to tree, he loooooves bananas, and in all likelihood he will never stay in one place for longer than a few minutes. Now let’s say you have something you need to tell Alan – you get him down from whichever tree you find him in, you sit him down on a chair, and you start talking to him. Only before you’ve even finished your sentence, to your dismay, Alan is off back up the tree. You try a few more times, and Alan very helpfully sits there for a number of seconds whilst you try and get your words out. But the same pattern continues, and in the end you give up.”
