An estimated 80 million young Americans, ranging roughly between the ages of 18 and 35, make up our millennial generation. They are expected to make up 36 percent of the U.S. workforce by next year and nearly half by 2020.

It's not surprising, then, that companies and organization and businesses want to understand this generation--who grew up in a world vastly different from that of their elders--and what motivates them.

Millennials' reputation isn't the best, unfortunately--they're known for their job hopping and impatience with bureaucracy. But there's plenty to feel good about, too. They're extremely well educated and culturally diverse, for example, and they know what they want.

Some think that the best way to win over millennials is with flexible work packages, higher salaries and great benefits. But what truly motivates them runs deeper than you might expect:

Opportunity to sharpen their skills.
Leveraging technology.
Instant gratification.

To motivate our millennials is not difficult--and once you understand their motivation you can get them more engaged and involved. And once you gain their buy-in, they give you their best.
