I think others have covered the time and discipline/planning well enough. As far as the financial aspect, ebooks can be found very cheap or free. Also, you can utilize eBay, used book stores, libraries, etc.

Cormac McCarthy has some good stuff. I really liked The Road and No Country for Old Men. I've heard Blood Meridian is really good but very violent.

PROOF: Finding Freedom through the Intoxicating Joy of Irresistible Grace by Daniel Montgomery and Timothy Paul Jones is one for me. It's the book that helped me accept the doctrines of grace.

RC Sproul has a bunch of books in the Crucial Questions series that are probably all under 100 pages and are all free for Kindle.

Every so often they put them on sale for Kindle for around $1.99. That's how I got all of mine.

I have several volumes in the Christ Centered Exposition series. I'm planning on reading one of those. They are edited by David Platt and Tony Merida.
Victor wrote: "The golden classic: systematic theology by Wayne grudem is a must read in this area."I want to read this but in the interest of reading books I already have and not tackling a 1300 page book while trying to read this many books, I think I'm going to read his Christian Beliefs: Twenty Basics Every Christian Should Know instead.

I would really like to get to the committed level but I'll probably be doing good to get to avid. It looks like this year I'm only going to finish 17 books. I used to read a lot more but time constraints with work and five kids have put a damper on it. Looking to spend less time on Facebook and such to read more.
