An Unique experiment..!!

You can try and prove that words has great power to every people whom hear, in fact affected our mind. Get 1or 2 friends. For example the target is" X". Remember, before the experiment finish, do not she know about it.
When you meet her, you must say " X, today you look so upset. Are you sick?"
10 minutes again, ask your accessary friend to say a different sentence but has same meaning to the X. After that see the changes on her. Maybe, she really feels hurt and become sick.
Vice versa, if you say a positive sentence to her. For example you say " You are suitable with your dress. You are very cool." Look the changes of her. Maybe, X become more confident. She become more spirit and her face always smiling.
This the power of word. Without experiment, we often try it. A few critic or praise from other will make us think about her sentences. Is it true? So, we be clever to select positive words. It will pump yourself, friend, brother, sister, or people whom you met.
So, one time you will be known as a motivator , do not as a crushers. Remove the negative  words in the your dictionary life. Promise that you will say special and the best words to the yourself and others.
The power of word is as a double-edged swod. If you use in positive event, it can give a big power. Otherwise, if it is used in wrong event, it will bring a catastrophe and loss to us and others. 
A polite and courteous words, and full of motivation will give positive contribution to us.  A motivation words will present the best side of our life. A beautiful unity will be established because of positive  word.  There is a something interest if we can give happiness to other. Because deliver happiness will double the happiness.
