Are you positive or negative?

The characters are diverse and not get two exactly alike. But as there are characters that are more marked in some direction. An example is the markedly negative people in their expressions and others are markedly positive. That is, the negative to all you say NO and positive easily say YES.

Realize if you are in any of these two groups. Perhaps you have said, or maybe you've heard comments about you. 

And what to do? Switch to a way of being more consonant with the ideal character, you should know when to say yes and when to say it should not.
