To clarify, this whole thing about using 10%, or 20%, or whatever % of our brains is 100% false. we use all our brains. In the 1930's psychics started the rumors that we only use 10% of our brains and that they had figured out how to use it all and that's why they are psychic. if you ask any neurosurgeon and otherwise person experienced in the brain, they'll tell you it's just a popular myth. but, you tell a lie a million times and pretty soon it becomes a fact that people take for granted.
