You may want to tweak your titles to give readers a little bit of information on what your article is about.
For example, instead of "love story movie" you could make it "Movie Review: Love Story" or something along those lines so that readers know they will be reading a review of the movie.
On your hub titled "Happiness"... What are you saying about happiness..? That it's good? That it's something people shouldn't strive for? Upon browsing your article , I see that it's a how-to guide. Let readers know that... I suggest changing the title to something more appropriate for the subject: How to Live a Happy Life
or How to Be Happy
I recommend going to this hub: http://hubpages.com/hub/How-to-Improve-Your-Hubs
and read the section called #1The Title
There are some articles that I link to in this section that I HIGHLY recommend you check out, not only to improve your title, but your hubs in general... so you can get higher hubscores and more traffic.
