definition
the ability to acquire and apply knowledge and skills
intelligence is essentially excelling at something or being able to fully grasp a certain concept. intelligence is not just book smarts and memorization skills, it is much more than that. intelligence is the willingness and ability to learn and thrive in something and use those skills to your advantage. intelligence is not having a one track mind, and being open to new ideas and different ways of thinking that could potentially make that person better at what they do.
pablo piccaso and albert einstein are both intelligent even though they excel in different things
