Copying from answer : "Excessive pride occurs when you overvalue your assets and achievements, which usually leads to vanity. This is not the belief that you can accomplish more than others (unlike arrogance), but the belief that you are better than others thanks to what you have or do.
If you believe that your beauty, for example, makes you better than an ugly person, you are vain. If you are proud of how beautiful you are, but remember that it does not make you better or worse than anyone else, then you are proud without being excessively proud."
