FYI look at these sites, there is no scientific evidence of the 10% myth. Dribble. Absolute rubbish.
If we use all of our brain's potential, how can we ever increase the level of our intelligence at which we are now?
You're thinking that the myth says "we use 10% our our brain structure" and that the other 9 out of 10 pieces just sit there.
Potential vs. Structural Usage.
Further, William James, the originator of the myth was the #1 proponent of Pragmatism. How pragmatically useful is it to you to believe that you use 100% of your brain? If the '10% myth' is a lie, it's a good one. It's one of those 'lies of success'. Why? It's functional; it serves me to believe that I have so much potential to expand.
Drew,
Where are we going and how can I get there?
Try some drugs

Pyschedellics and Nootropics. I have not tried either, and probably never will--unless they are legal. But that doesn't stop me from researching about them!
