Ok...I've had about enough of my wipers

...I don't know what I'm doing wrong...but they skip and sound hella annoying ...Can anyone give me some advice or tips on how to get the wipers to work normally again? Is it because the spring that applies pressure to the windshield is wearing down? Anyone else ever have this problem? Am I buying the wrong type of wiper blades?
ANY SUGGESTIONS OR SOLUTIONS WOULD BE GREAT!
