What did you learn from these intelligence quotes?
When you think about the smartest (or most intelligent) people you know can you recognize any common traits?

They seek out new information all the time, whether that is through formal education or just grabbing a book and learning how to do it.
Another thing you might notice is that they also seem to have a good grip on their emotions and display a high degree of emotional intelligence.
Most likely, the people you think are intelligent are also aware of what they do not know.
They are aware of what they need to learn more about and will let you know if they don’t know the answer.
Then they will most likely go seek the information out.
They are often highly adaptable and can make the most out of whatever situation they find themselves in.
