Why the "YES" is preferable over "NO"?

Yes, when I say yes, most of the times because I am agreeing the things and while I say no, I am denying something to happen around.There is an agreement whenever its "yes" and for a person in a society containing people of similar interest it becomes easy to get a positive response for him/her.

So if yes means the positives then it would also mean the constructiveness and it straightway depicts the behavioral context of a mind as the negativeness (saying "no" most of the times) creates a boundary around the mind and every time mind will concentrate to jump over the wall and will not let a person walk with the fellows around and as a contrast "the yes" does not stop you to be innovative as yes does open more and more horizon. One affirmative thought for any small thing make is bigger and bigger as it progresses in terms of time.One example- If I liked a thing ,I am agreeing on it and through this I will try to find more about it and this way the knowledge thickens and if required/practiced it turns into the actions and innovations.

It does work the same-way in workplace or personal life both.If at work I do agree the things more then the people around me will have to agree to me and this will create a better environment that can lead to many benifits.
