The human brain is a fascinating “device”, which allows us to function and makes each of us unique. It’s our Central Processing Unit (CPU), and unlike the CPU in our computers, we cannot replace our brain with a faster one. So then how do we evolve and make our CPU run faster and more efficiently? I guess nobody has that definite answer yet, but I got some clues about improving the way we think / solve problems / generate ideas from one of my favorite books, Refactor Your Wetware. (btw, this is a great book, do read it.)
Consider the image below, which I find is a funny metaphor of our brain (borrowed from the book).
