According to Dr. Joe Dispenza, our brain processes 400 Billion bits of information per second and we are only aware of 2,000 of them.
These 2,000 bits of information is the capacity of our focus and it feels like a tiny flashlight pointing at a huge pile of information, searching for the relevant one.
Therefore, writing can be seen as choosing the right words, the rights bits of information from the huge cluster of mostly unidentifiable bits of information.
When you can’t find the right word or you can’t write at all, it means that something is wrong with your flashlight.
It’s either pointing at the wrong direction or your battery is low.
To solve the first problem, you need to change the point of view and to solve the latter you need to take a break.
