Could you give me some examples of both words being used?
For Vanity:
"The man's vanity caused him to neglect his lover, as he could not see past himself enough to truly see her."

For Hubris:
"The woman, in her hubris, took on a challenge that would prove to be too great and brought about her own demise."
Please define the difference between vanity and hubris Vanity is an overabundance of interest in one's appearance or achievements, whereas hubris is a misguided belief in one's capabilities.
