FYI: The level of a person’s raw intelligence, as measured by aptitude tests such as IQ scores, is generally pretty stable for most people during adulthood.
While it’s true that there are things you can do to fine tune your natural capabilities, such as doing brain exercises, puzzle solving, and getting optimal sleep – the amount of raw brainpower you have is difficult to increase in any meaningful or permanent way.
For those of us who constantly strive to be high-performers in our fields, this seems like bad news. If we can’t increase our processing power, then how can we solve life’s bigger problems as we move up the ladder?
