MCSE Confidence Level

Good Morning Folks
So I am starting to study for MCSE, amongst other certifications. I work for a small\medium size company (around 100 employees) and I manage our systems along with our engineer. I am mostly responsible for 1st and 2nd level support. I manage some of the basic AD stuff. Some VMware\VMware View environment as well. I got the Mastering Windows 2012 book from Mark Minasi. I also have TrainSignal and CBT Nuggets training videos, plus other PDFs\eBooks on the subject. I am not in a rush. I will take as long as I need to do to master this. I have a lab environment, plus my live environment where I can apply my knowledge.
Here is my fear
I lack confidence that I will be able to learn all this stuff. I look at the book and there is just so much information that I feel overwhelmed. I don't want to start out by thinking I am going to fail and I am not a dumb person, but I am looking for some opinions and suggestions here. Is this something that just takes a lot of education, practice, and time, or do I have to be some kind of a genius to learn all this? I know its kind of lame question, but I do feel a bit overwhelmed that this is just too much too learn and understand. I am especially concerned about learning PowerShell commands. All the scripting\programming is giving me a headache just by looking at the information in the book.
Anyway, any thoughts here would be greatly appreciated
Thanks,
Felix

I feel like just reading for me isn't enough, I needed a lab set up for me to see everything in action.
With Virtualization it's so easy to lab at home now
I've been in IT for almost 20 years, but its always been more on the client side and doing independent consulting for home users and small businesses. This is advanced stuff and I am trying to decide if this is something I want to do. Don't get me wrong, I love this stuff. I love technology. I just don't know if this something I can learn on the level I am supposed to understand it to get a much higher paying job. I am 38 and this is a time for me to decide, am I going to advance in what I am doing right now or is it time to change my career before its too late?

Essentially the exams are just a memory test, most of the concepts aren't difficult and if you use powershell etc. in your day job then you've got a good starting point so just focus on one exam at a time.
Basically, go look at the Windows Features & Roles list in Server 2012, and that is what you will be learning.
I took the exam twice already and failed. First time it was about 450+ and the second time I got close to 500 score. All you need is to move forward and not think about if you will pay it or not. Age doesn't really mater I been in I.T for about 15yrs myself.
Just start from scratch and move forward.
My Goal for the Future
2012 - *MCSA*(WHO KNOWS WHEN) KEEP FAILING!!!! Not enough time to pass the last 2 exams.
2021 - *Security+*
2022 - * Pen Tester*
