Fellow Bloggers, I need HELP with my blog!!!!!

Hi Bloggers! Ok, so on my blog I have this "you might also like" feature under each of my posts. I have noticed that a lot of them pretty much show the SAME EXACT pics and posts rather than a large assortment from my other posts.

Does anyone know how to get it to rotate the posts out more? by that I mean, how do I get the "you might also like" to show more of a variety of my past posts instead of showing all the same ones?

If anyone knows how to fix this or change the feature, please help!

Thanks!!
