Andrew Chan

The more positive you are, the more positive your contributions will be, and the happier you will be at work. Like begets like, and positive people are likely to create a positive mood or attitude in everything they do, with everyone they work with, and at any workplace they inhabit.

In other words: be positive, or you might as well not expect to make much of a difference.

Positive people do more and influence the people around them in a positive manner. Negative people influence too, but since their "aura" is negative, the results they are likely to have will be negative. In real terms, if there's any movement, the negative people tend to take an organization backwards, not forwards.
