How can I access 100% of my brain?

If someone says you can use your brain 100%, stop for a moment it's not a switch you can turn on. My grandmother used to say, "Everyone has the power, their attention is just scattered." The Brain Song brings that scattered attention together. When you listen to it, your mind doesn't wander to different parts it starts falling into a rhythm. I've noticed that when I work or meditate while listening to it, my clarity increases. 100% brain access doesn't mean becoming superhuman, but rather unlocking your inner peace and creativity. When the mind is calm, it is at its most powerful.
