I suck at Adsense earnings

No matter where I advertise my Adsense ads to my blogs, or to the other sites, I still suck right of them. Out of 1,500+ impressions combination of all of my sites for this week, I only received $0.17 in 50+ Adsense clicks. What’s going on? I’m not really contented to it, because this reminds me of earning in a low PTC (paid-to-click) site which earns only cents daily. My Adsense earnings right now just stick to $26.87 as of now and it’s very slow to reach $100. However, there should be a way in order to increase my Adsense earnings by just changing the niche and content of my blog. Forex and weight loss are better topics to take care of, as most Americans are interested about them. If I will advertise to high traffic sites, it’s not good enough because only 30% chance that all of the visitors may click my Adsense ads, but the revenue that gave me was not good at all, and it’s very low.
