55% Body language

This means when you are speaking to people the words you are using only accounts for 7%.
The way you use words has a far larger impact, it could be argued that is does not really matter what you say to people, only the way you say it.
The largest impact you have on people is body language, what are you saying with your body?
In varying circumstances body language can go up to as high as 93%.
This is true if you are on the phone or face to face.
So if you are there conversing or simply conversing with a client, use you body and you vocal tones to maximise the impact you have.
For example if you sit there slouched in your chair, speaking in a monotone voice, you are going to sound uninterested and lazy, simply go through the motions.
If you are doing an action, make it count, it more interesting for you and will bring more success.
Example; your conversing for the afternoon, you could make 200 bad calls and get nothing, finish off board, having wasted everybody’s time.
Or by the time you have finished off you 10th call the afternoons gone in a flash, you’ve been successful, times flow past and you’ve made money.
A pleasure, a fun afternoon joking with people or feeling depressed, your chose.
