Can anyone tell me what this quote means?

No one ever remembers what happened down to the last detail. It is a natural human response to exaggerate our memories. Sometimes to a greater extent then others. In the end, we always make the memory feel more real than it did originally. We manipulate it into a way that it has far more significance to us. Though in the end, like jewels, its the real ones that are worth the most, and are in the end far more significant and special then the ones we have manipulated.
