Where do I paste the adsense codes to make them show up on my hubs?

You don't have to do the copy and pasting Hub Pages will do that for you. After you publish a hub, hub pages automatically place ads for you so you don't have to do that.

Just make sure you have placed your adsense pub number in your affiliate setting tab.

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.
