Does the intelligent person have more brain cells?
The difference is to what degree they use what they have. Or how they use it… or for what…
It is said, that most people use 2-3 percent of their brain. That statement is not entirely true, they use more, but not for thinking.
The rest of the brain is used for fear based negative thoughts. Or to mill water… Ponder stuff that doesn’t matter, fret, worry, explain in your head… yeah, the stuff your mind is busy with.
