1. Condescending Remarks 

Arrogant people are single minded; they either think that they are superior to others or inferior to them. This arrogance may be nothing more than a way to cover the feelings of "feel small" they experience when dealing with someone else. They feel better when they tears others down. I think it's truly a sick feeling to see that behavior, because I feel allergic to people who always think they're superior and better than everyone. Wake up! There's always people who's better than us, and we should never stop learning. 

On the contrary, confident people are high minded, because they can feel good without having a desire to offend or even hurt others. They don't feel the need to brag. They usually see other people's potential and can help them succeed in something.  

2. Active Listening vs Monologue

Arrogant and confident people treat others in a different way. An arrogant person thinks they are better than others, while a confident person knows they are just as good as others. 

Confident people will rarely be found lecturing to others or how they are wrong. They usually show respect while listening to somebody. Arrogant people have difficulty listening to others/ They often exude negative energy and blame others if things do not work out as expected.

3. Ambition vs Ruthlessness

Ambition is not a crime. Confident people enjoy achievement and contributing their talents to the world. They don't feel threatened by others' successes and instead try to LEARN from them. 

Cocky people need to believe that they are on top even if reality says otherwise. This can lead to unnecessarily manipulative behavior as they focus on defending a power base at all costs.

4. Self-perception

Confident people always feel comfortable, because they have the right conception of perfection. It seems impossible to bring them down, because they are aware of their weaknesses and know how to deal with them. Meanwhile, arrogant people brush their own weaknesses aside and cannot admit their mistakes.

5. Communication

Of course, it's not a pleasant thing to communicate with this kind of people. An arrogant person will always try to one-up everything you say. They mind only their own position and make others accept their ideas. That's why people try to avoid their conversations with them because it's not comfortable to speak with the person who is always right. Yes, ma'am lol.

Confident people ADMITS lack of knowledge and they don't try to impose their vision of the situation on others. Their accomplishments do it for them.

6. The Human vs The Greek God

According to psychcentral.com, as a self-confident person, you accept that you are just a human being. You are intrinsically no better or worse than anyone else. You accept who you really are, you have flaws, failures and really bad hair days. You treat yourself with compassion while taking responsibility for your choices, and you learn from misfortune and mistakes. 

Arrogant people can't risk the fragile image in the face of the defeat and run from criticism. They tend to go extremes of either deflecting blame onto others or condemning themselves for being only human. 

Truly secure people evaluate their own behavior and fave their doubts. By letting go of fear, you set yourself up for success.

7. The Origins

Arrogance is usually the result of a defense mechanism used by subconscious mind in order to prevent further criticism. Confidence comes from positivity, optimism and mental steadiness.

Well, that's it. I think it's important to understand the differences or the fine line between arrogance and confidence. Because no one likes to deal with arrogant people. This article is also for myself, so I always remember to stay grounded, yet confident. Try to be confident, because everyone wants to hang around people who feel secure and positive. No one wants to hang around cocky persons. Have you ever dealt with an arrogant person? Can you tell the difference between arrogance and confidence?
