We spend a great deal of time trying to figure out the right things to say in class, work, interviews, relationships, etc. Pretty much every aspect of our lives. Often, we forget that our body language factors into this equation.

More than the awful Heidi Montag single, body language is extremely important when trying to present yourself. I decided to look up body language tips. Here are some of the ones that I found the most helpful.

POSTURE: I’m sure you’ve heard this a thousand times, but putting your shoulders back and aligning your back makes a big difference. Not only does it make you look more presentable, but you also appear more confident. Also, remember to keep your head up.

FIRM HANDSHAKE: The handshake applies primarily to job interviews. But, anytime you have to shake a person’s hand, do so firmly. It shows confidence and that you know how to take charge.

EYE CONTACT: It is vital to maintain eye contact with the person you’re talking to or the person who is talking to you. Looking around the room can be interpreted as boredom, dishonesty, or disinterest.

ARM CROSSING: Unless you are engaged in a confrontation, crossing your arms shows that you are either feeling reserved or defensive. Both literally and physically this gestures closes you off.

HANDS OFF: Keep your hands out of your pockets and off other places on your body. Touching your neck or twirling your hair can lead someone to imply that you feel uncomfortable. Even if this is the case, try to keep your hands folded in front of you.

LEGS AND FEET: Tapping your feet or twitching your legs, while they may be signs of nervousness, it is also a distraction and shows that you are anxious to leave.

According to Forbes.com a recent study found 55% of a first impression is determined by body language. Now that you know these useful tips, you can prevent yourself from giving out mixed signals.
