Perfect your posture.
Pull your ribcage away from your pelvis, roll your shoulders back and down, pull your stomach in and tuck your bottom toward your spine. Breathe deeply. You'll not only look better, but feel more energized, alert and in control.

Think before you talk.
Think fast, pause, then speak purposefully. One CEO practices saying everything to himself before he says it out loud so that he will hear how it sounds and can change it if he needs to.

Slow down.
Speed in speaking, moving, gesturing and walking looks nervous and scared. Scared people get passed over, not hired or promoted. Learn to speak in a comfortable, easygoing and welcoming way. Don't waste time, but do speak as if you have all the time in the world for those you are speaking to.

Shoot straight.
Everything you say or write can be done in a simple, straightforward manner. Just do it.

Be a good storyteller.
People understand you better, remember what you say longer, and find you smarter and more interesting if you use anecdotes to make your points.

Be aware of your style.
Clothes don't make the man but they do make a difference. Wear well-tailored, good quality clothes that make you look like you are in charge. But remember, it isn't as much about your look as how you look at things and what people see when they look at you.

Admit your mistakes.
If you are error-free, you're likely effort-free.

Don't be bullied.
If you are unjustly criticized, don't take the bait and get into an argument. Instead calmly ask: "Why do you think that?" "What do you mean?" or "What's that based on?"

Be flexible.
Be able to stand out while still fitting in with the crowd.

Be at ease with yourself and others.
Look others straight in the eye, eliminate any defensiveness and take the edge off your voice. Never let them see you sweat!
