Feeling brash and sassy? Self-confidence is a good thing but when you’re always the office know-it-all it can backfire — especially if you are so full of yourself that you don’t care. The result: an arrogance that makes colleagues unwilling to work with you.

We turned to question-and-answer site Quora to find out how to deal with an arrogant person at work and beyond. Here’s what respondents had to say.

The ego at-large

“Arrogant people need attention like all others need oxygen,” wrote Angie Neik. “They need praise and admiration like it's the end of the world. Give it to them up front.” Otherwise, you could “walk away, or spend hours arguing (yes, arguing, because arrogant people have no concept of a conversation or dialog), that will leave you exhausted.”

But remember, Suretta Williams, noted:“People who are truly great, don't boast about it.”

The nerve!

Sometimes arrogance stems from intelligence. “My experience has been that a lot of arrogant people are either very intelligent (or think they are) or successful... or a combination of both,” wrote Anna Butler. “Those who think they're intelligent (rightly or wrongly) struggle to understand why everyone doesn't think the way they do. Those who are successful and arrogant also struggle to understand why others can't strive as hard as they do to reach the same level of success.”
