Intelligence

How do you know if someone is intelligent? I think it varies from person to person, especially if your one of those people who think you are intelligent, but are in fact not. I belive to be intelligent you definately have to have knowledge about life, which is wisdom. What's the point of being intelligent in school and not life. Great intelligence I think is when you come up with great unique ideas about life and they're better than anyone could have ever thought of. Uniqueness is in other words a great form of intelligence. Most greatly intelligent people are also the ones that don't even know they are. Basically, you know if someone is intelligent if they have great wisdom and make great choices.
