Question: why are my pictures blurry on auto? not crisp and clear always?

I just purchased the sx 30 is after reading countless reviews on cameras at this price point and with the list of features. however I am not able to take many good pictures, all my pictures come out blurry and I see so much motion.. what am I doing wrong? Shouldn't the auto feature correct the motion? Is there am not using or something I need to adjust? Please help... I was so excited when I got this, now I'm disappointed.
