As an exercise in emotional intelligence, seek out a "loving critic". A "loving critic" is someone who you respect and trust to provide you with honest loving feedback about how you come across to others. This will help in developing a mindset for continual growth and will help to develop your self-awareness and self-management skills.
In addition, learn from others. Seek out others who you have observed remain calm under pressure and who are good at giving and receiving feedback. You can learn from them the ways in which they practice emotional intelligence.
