When computers were being
developed, they tried to make them work like our brains. They couldn't and still can't do that. They can get computers to do one task sort-of-a-bit-like our brains. But not the fable of multitasking most people chase each day. The way in which the world has moved on, now we somehow expect our brains to work like they envisaged computers would!
Our brains are not designed to run on multiple tracks simultaneously, staying with that highly praised fable of 'multitasking' makes people tired, irritable and yes, less efficient.
Watching any craftsperson, artist, etc as they become absorbed in the focus of their work, moving up close to what they're actually doing. By not overloading or multitasking, the neural process is free to be creative, with art etc. yes, but also with problems solving, learning new skills. Living life, our own life – So don't just do something – sit there!
