What is a Millennial?

"Millennials grew up in an electronics-filled and increasingly online and socially-networked world. They are the generation that has received the most marketing attention. As the most ethnically diverse generation, Millennials tend to be tolerant of difference. Having been raised under the mantra "follow your dreams" and being told they were special, they tend to be confident. While largely a positive trait, the Millennial generation’s confidence has been argued to spill over into the realms of entitlement and narcissism.  They are often seen as slightly more optimistic about the future of America than other generations -- despite the fact that they are the first generation since the Silent Generation that is expected to be less economically successful than their parents.

One reported result of Millennial optimism is entering into adulthood with unrealistic expectations, which sometimes leads to disillusionment. Many early Millennials went through post-secondary education only to find themselves employed in unrelated fields or underemployed and job hopping more frequently than previous generations. Their expectations may have resulted from the very encouraging, involved and almost ever-present group of parents that became known as helicopter parents."
