How do you study for CCIE?

Reading allot of blogs out there, there seem to be quite a few different approaches to studying for the CCIE. Some people read entire books, go through full COD type classes and then go on to either protocol labs or multi protocol labs. Others well read and wing the exam, some are actually successful some are not. Some just do Mock Lab type scenarios.

I for one do this, first I'll read a chapter in a book about whatever subject I happen to be on. For this I'm going to use OSPF. I read that chapter on lets say, Routing TCP/IP by Jeff Doyle.. (Awesome book!). Rather than read the whole book, I go to lets say my Internetwork Expert COD and go through the OSPF videos. Then afterward, I open up an OSPF specific protocol lab, in this case Internetwork Experts' VOL1 labs. Then go through my notes during the lab practice or after, refresh on anything and move on. Only after I've fully done all protocols in this scenario, do I move on to full protocol labs or mock labs.

What is your study habit? How do you prepare? Any pointers, comments or advice more than welcomed.
