More about sharing aspects on Astromarkt and about the Moon in Sagittarius in the article about the Basics, too. I quote:
Well, you may not really BE cheerful, but you think acting cheerful is a good thing always. You need progress and good news, cannot do without and when you pretend being happy you might actually become happy (you hope). Sometimes you just overdo that! When things are getting wrong or bad you became nervous and hurried.
Billy Graham is a good example of this positive attitude.
See them sing on YouTube...
