''Anyone can become angry-that is easy. But to be angry with the right person, to the right degree, at the right time, for the right purpose, and the right way-this is not easy. ''
Aristotle, the Nicomachean Ethics.

When we talk about intelligence we are almost always reffering to 'mental' intelligence, or QI. A whole language has grown up to describe degrees of intelligence, we say of people that they are 'bright', 'brainy', 'Einstein', 'dim', 'thick', or that they have 'nothing between the ears'. EI (or EQ) has only come into the language in the past 10 years, but colloquialisms for aspects of it have been with us for far longer than that and, indeed, crop up all of the time.
Emotional intelligence is the idea that emotions are useful; they are important source of information. Emotions help us solve problems and they guide our social interactions. And, importantly, some people harness the wisdom of emotions better than others.

Mayer published the first scientific article describing a theory of emotional intelligence in the journal Imagination, Cognition and Personnality, it wasn't sure that anyone would find the idea that people differ in their abilities to identify emotions, understand these feelings, manage emotions, and use them to guide thinking and action all that interest ling or persuasive. But today, while wrinting this forword, you typed the phrase 'emotional intelligence' into google search engine, and it yielded more than three million hits. Interest in emotional intelligence has exploded, and we know a few things now that we didn't know two decades ago.
Ever since it came into prominence in the early 1990s, critics have dismissed the idea of EI as a passing fad. However, Daniel Goleman argue that in the workplace possessing mental intelligence is just not enough any more. Indeed, intellect alone is never enough, because many of the problems they encounter are essentially emotional in nature.
