They are not truly grasping the concept of entrepreneurship.

“Too many Millennials are confused about the distinction between becoming an entrepreneur and doing something entrepreneurial. We read a lot of statistics about how many Millennials want to work for themselves someday because they’ve grown up in a society where technology has taught them that anyone can do anything. That is not the case. So, what should they give up? They should stop believing that working for yourself is the only – or even the best – way to learn what it takes to be an entrepreneur, make a significant difference, and effect change.”

Excessively arrogant.

This one has become nearly cliched, but we still hear about it.

“The issue is that there is a link between self-motivation and entitlement and a fine line between confidence and arrogance. Millennials put in a lot of effort, and their desire for meaning drives a lot of them to be intrinsically motivated. We must recognize that the feeling of self-purpose we have CREATED for ourselves is no more significant than anyone else’s.”

I was being overconfident.

“We Millennials may be extremely self-assured, which can be energizing and inspirational to people around us—but only when it’s genuine. Bottom line: Don’t appear to be an expert if you don’t know the answer to a question. It’s fine to be unsure, and it’s preferable to be open about it rather than project a false sense of certainty.”

Inability to concentrate.

“I’m a Millennial, and I lead a company where Millennials make up most of the workforce. The terrible habit I’d want to bring up is the inability to focus due to continual distraction. Generation Y was raised in front of a television, surrounded by fresh stimuli every 15 seconds. As a result, many people find it difficult to regain their capacity to focus for extended periods. The internet and mobile devices aren’t exactly helping to break this habit.”
