In both your professional and personal life you will need to develop your emotional intelligence IQ which is usually referred to as your (EQ).
Communication is key to success in any relationship so it is very important to hone this skill of understanding the emotional state around the person that you are interacting with. An example of this is seeing someone that you want to communicate with is sad, you will naturally change your approach in how you open your conversation with them because you can visibly see they’re sad. The same would go for any other emotional state as you want to have the most pleasant experience when interacting with another person. This is the most basic way of looking at this skill set but this understanding can go much deeper along with being useful.
The understanding of emotions and the best way to manage them is a great way to ensure that you will always have a constructive interaction with anyone you meet. Keep in mind you need to be aware of your own emotions and manage them as well. Knowing your own personal tendencies with emotions will allow you to manage them to be a more effective communicator.
Having these skills allows you to effectively understand the best way to approach and communicate with another individual in any situation. This can be a very important tool if you are ever in leadership or managing people as you need to have a grasp on the best way to approach your employees. It can also be very good at diffusing tension between individuals or uplifting people that may be down.
Overall, emotional intelligence is an understanding of how people feel and work, which allows you to be a more effective communicator, motivator or leader.
