Controlling our emotions is important since it will be a life skill that you will have to learn how to manage. For example in a relationship or a job. In a job you can’t show customers that your upset you have to remain calm.
Not controlling your emotions can lead to something that you may regret in the future. Let’s say I was at school and some kid made fun of me it would be smart of me to control my emotions and walk away but it wouldn’t be if I tried to fight him.
