Why do we use metaphors in English?
We use metaphors to explain complex and abstract ideas using familiar physical things. Comparing emotional insecurity to a heavy backpack or a cracked foundation makes the mental state much easier to picture. This helps listeners grasp deep concepts quickly and remember them better.
How can I use these metaphors in my writing?

Are metaphors the same as idioms?
Metaphors compare two things by saying one thing is another, while idioms have a figurative meaning different from their literal words.
