The above answers are correct about Google Adsense. Do not click on your own ads. Google is very particular about protecting their advertisers and will suspend your account for a variety of different things including clicking on your own ads.
I have a couple of my own sites with very profitable Adsense campaigns that Google had suspended and I hadn't clicked on one ad. The kicker is Google does not tell you what you did! After some considerable research and a lengthy appeal to Google, they reinstated my account. My conclusion is that they suspended my account due to multiple refreshing of pages. When I would edit pages or posts on my sites I was always refreshing the page to see how it looked. You actually get paid for impressions with Google Adsense and they consider multiple refreshes with your own browser as a violation of their policy.
As far as Amazon is concerned, you can order products from links in your hubs but you will not get any commission credit for the order.
