Need help raising CTR

http://rapidlysharing.com
This is my second real adsense site my other one was just a proxy and was making like 30 cents a day or something like that so I pretty much gave up on it. I am getting about 1500-2000 impressions daily and I have a ctr of less than 0.5%. I see people on here with CTR’s of 20%-30%. How can I get that!? Or atleast higher than what I have now. Please help me out.
