Living in a fool’s paradise

To believe wrongly that your situation is good

The most appropriate meaning of the idiom "living in a fool's paradise" is to believe wrongly that your situation is good.

The idiom is used to describe someone who is deluding themselves about the reality of their situation. For example, you might say that someone is living in a fool's paradise if they are ignoring the signs that their relationship is in trouble, or if they are believing that they are going to win the lottery even though they have never bought a ticket.

The other options are not as accurate descriptions of the idiom.

• To be fooled by someone suggests that someone has been tricked or deceived, which is not necessarily the case when someone is living in a fool's paradise.
• To live in luxuriously after fooling someone suggests that someone is living a life of luxury because they have tricked someone else, which is not always the case.
• To live in a world of imagination suggests that someone is living in a fantasy world, which is not the same as deluding themselves about the reality of their situation.
