The problem with the word "smart"

"Smart" is one of the most common words used to describe a person.

And yet this tells you absolutely nothing about that person.

Oh, Chloe is great. Just great. Really smart guy.
The problem is "smart" is used in place of an actual positive description.

Oh, Chloe is great....
She processes information quickly.
She works really hard.
She is good at connecting with people and making them feel heard.
She is a great organizer of information.
She gets a lot of things done and always produces on time.

Next time you are calling someone else (or yourself) "smart" stop. Think about what you're really trying to say, and just say this instead.
