Final answer:
Emotional intelligence is the aspect of success involving self-awareness and emotion management; it's crucial for social interactions and can predict success.
Step-by-step explanation:
The aspect of success that involves the awareness of one's own emotions and the ability to manage them is known as emotional intelligence.
Emotional intelligence includes the skills of being able to understand one's own emotions, exhibit empathy towards others, navigate social complexities, and regulate one's emotions to respond appropriately to different situations. This concept relates closely to Gardner's theories of interpersonal and intrapersonal intelligences, and it has been suggested by researchers like Daniel Goleman to be a key factor in predicting success, sometimes even more so than traditional intelligence assessments such as IQ.
