Any tips for WAN learning strategy?

I have found the WAN concepts to be my weakest point, and one of the main reasons I have not taken the CCNA yet. I think that it may have to do with the way the material is being presented to me. Does anyone have a source that shows the WAN protocols/encapsulations that can be used why and when? Sometimes I am just thinking, why would I use HDLC instead of PPP encapsulation? And if the network is packet switched, what encapsulation should I use and why? Seems like the books just scatter the material in a random manner, and not laying the foundations down the way I would think they would. If anyone has a good source for understanding WANs I would appreciate it. I already have all the Lammle and Odum books.
