Developing Self-Control
RocheMartin defines Emotional Intelligence by a set of 10 competencies and this is one in a series of blogs covering each one.

Self-Control means you're able to let go of negative emotions quickly, so you can think logically, focus on what needs to be done and move forward in an organised way
The 3 components of Self-Control are
Calmness
Being able to let go of or stall negative emotions so you can stay calm and keep a consistent mood, whatever is going on.
Rational minded
Able to stay focused and not let your mind be hijacked by negative emotions.
Disciplined
Going about things in a logical, orderly manner and being accountable for what you do.
