Rose Colored Glasses

Whenever I watch Pollyanna, I always think "man she is perky... and kind of annoying."  But then I always wonder if I wouldn't be better off viewing life through Pollyanna's Rose Colored Glasses.  In the movie, one little person's ability to see the world in a positive light and focus on the good in people rather then the negative changes a whole town.  Is this really possible?  As a graduate student studying counseling and psychotherapy, I find myself challenged to find out if changing my mentality about situations I find myself in can change my enitre outlook on life, as well as others outlook on life. Wish me luck!
