Do you sometimes feel like you're the person others are talking about when you enter a room--and not in a good way? Is there uncomfortable energy around your office at important times, like presentations or meetings, but you never know why?

Well, it could be that you're engaging in one of these 7 work habits that make you look really unprofessional--all without knowing it. Step back for a moment and take a look at your behavior--and change it if you need to.

Are you in the habit of...

1.Interrupting people

There's nothing worse than someone who doesn't know when it's his or her turn to speak. It shows a severe lack of respect to cut someone off before they've finished articulating their thought.

2. Talking too much (about something you don't know)

This goes hand in hand with interrupting others. Usually, if you have a lot to say, you'll ache to get it out. But, if you've noticed that you have a tendency to raise your voice--even when you're clearly uneducated about a topic--it'll reflect better on you to simply stay silent. Promise.

3. Always being late

While certain cultures have a penchant for arriving everywhere a couple minutes late, it unfortunately isn't a trait that looks so good in an office setting. Make a point of leaving your office a few minutes early to keep your colleagues from shooting you nasty glares when you walk into your next meeting 5 minutes late.

4. Not cleaning up the communal space

Don't leave dirty dishes in the office kitchen. Throw that stray piece of paper away. Being messy might have been cool when you were a teenager, but it definitely isn't when you're a grownup at work.

5. Complaining

We all get tired, sad, and angry. Not all of us, however, always vocalize what we're feeling at every moment of the day--nor is it necessary to do so. Quit complaining at work, and your coworkers will surely be grateful.

6. Looking like a slob

While many offices have adopted a "business casual" dress code, that doesn't mean that you can or should show up dressed like you're ready to spend a day at the beach. Dress well--even if you're dressing casually--and be well groomed.

7. Texting

You shouldn't text your friends, relatives, or loved ones while working, no matter how easy it may be to do so. People notice, and nobody finds it appealing. Oh--and lay off the Pokemon GO in the office while you're at it.
