Many believe that intelligent people are born. This is far from the truth. We are all born with same brain. Each brain has one trillion neurons. The more we use the brain, especially in our formative years up to 12 years, the more neuron connect with each other into a very large complex web within our brains. In other words the more we use our brain the more it develops and manifests as intelligence. The process is similar to building our physical bodies. The more we exercise the more the muscles develop.
