They command attention whenever they walk into a room. But the truth is, they weren't born with a confident gene. Instead, their daily behaviors contribute to their self-assured personality.

That's good news: It means anyone can adopt the habits confident people practice on a regular basis. Below are just some of the ways those with extra self-possession approach life differently than everyone else.

1. They're more productive.

Confidence = hustle. Research suggests that confident people may be more productive because their can-do thoughts inspire real action. It's no wonder confident people seem to own the office.

2. Their body language helps boost their confidence.

3. They aren't self-assured all the time.

All people have their flaws, even people with the "it factor." The difference lies in recognizing those insecurities and carrying on with life despite them. Research shows self-acceptance is paramount to a happier life, but it's a habit many people rarely practice. Confident people aren't superhuman -- they just accept their imperfections wholeheartedly and live a happy life regardless.

4. They actively pursue success.

The research found that more likely someone is able to picture themselves achieving their goal, the more likely they're going to be able to do it, Fast Company reported.

5. They channel their inner celebrity.

A confident person's mantra is "I am Beyonce." OK, maybe that's just this author's, but regardless, there's power in celebrity. Research published in the journal Personal Relationships found that when people wrote down qualities they shared with their favorite celebrities of the same gender, they felt much more compelled to become their best selves.

6. They stick to their convictions.

"Other people are well meaning and sometimes err on the side of caution," she wrote. "Confident people listen to other people but do not let their difference of perspective take them off track."

7. They don't fear failure.

All people have their setbacks. Confidence isn't doing everything right, it's pushing on even after being wrong. And sometimes that can pay off in more than just confidence: Research suggests that people who appear more self-assured are also seem more intelligent.

8. They're not afraid of being confident.

Confident individuals don't shy away from asserting themselves, whether they're actually feeling comfortable or just faking it until they make it. As singer Demi Lovato's recent single so poignantly asks, "What's wrong with being confident?"

The answer: Nothing at all.
