7. You are/were the wisest person to do that. [meaning; Generally wise people don't do such a thing.] (The meaning is different from what you think. You are the wisest person...means that you are very wise/you have the utmost wisdom. For the meaning, "generally wise people don't do such a thing", let me suggest: You are/were wiser to do that. This means wiser than most others.
