When you applied for AdSense you had to apply via HubPages and you had to submit your hubpage profile URL from what I remember. I am surprised that you got approved by submitting a URL of one of your hubs and not your hubpage profile URL.
Remember that the total number impressions you see in your AdSense account does not equal the total number of impressions or views of all your hubs. So what you see in AdSense may actually be the correct number.
The key part in MM's answer is set up a channel to just hubpages.com in your adsense account.
That way it will track any hub you have here.
Unfortuanatly it took me almost a year to realize this I've been getting no credit for any of my hubs. Because when I first did mine I copied the URL of my hub profile page. Ughhhhh!
When applying for ad-sense, use your profile link.
For example, do this, when logged in hubpages, you see "my profile" on top right corner, click on it, then copy the link present in address bar of your browser.
Even if you have no channels set, clicks should still show up in the "aggregate view". You just won't know exactly where they came from.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
