Having emotional control takes practice; it’s a skill that you have to work to develop. It doesn’t just happen overnight. Developing emotional control is an important part of human development, as well. Not having emotional control can be a problem for decision making. If you're not aware of your own emotions, or how they dictate your decisions, the negative effects can affect your ability to make good choices. You don’t really understand the full scope of emotional control and how it can influence decision making until you are in a situation where you didn’t have any.
