Can being positive rub off on others?

Can being positive rub off on others?  Gosh, I hope so!  For the most part, I am a positive, upbeat person.  I'm one of those irritating morning people who greets everyone.  Most people respond positively, but some people can't stomach a happy, cheerful, "over the top" person.  You know what I say to that?...too bad!!  I truly hope my positive attitude and happy outlook rubs off on others.  I know when people are surrounded by negative people, that rubs off on others VERY QUICKLY.  Negative people are looking for followers, looking for reassurance.  Don't buy into that.  Being negative = being miserable.  Fortunately, I will agree that the majority of people are somewhere in between negative and positive.  Life is full of peaks and valleys. I hope to see you singing on top of the peak more often than not!
