Monty,
Just wanted to say good luck! I lost my day job last year and have been in the same situation you are in, i.e. sifting through the mountains of ebook data, programs, indecision, confusion and procrastination.
Being in the same situation as you, literally... I have a wife and three children... my first piece of advice is this. Talk some more to your wife. It is great to have teamwork here on the forum and on the internet, but in the long run it is better to have teamwork at home. The prospect of a husband bringing in NO money is one of the scariest things a woman can face. It affects every piece of a wife to think she and her children may not be provided for.
It sounds like such a cliche but many times what you get is something like:
Wife needs dependability and proof of nurture to feel secure VS. Husband needs feeling of freedom and personal accomplishment to feel alive...
Let her know that providing for the family IS THE MOST IMPORTANT thing for you. That this is all about doing that better, BECAUSE you love them. And really let her know how you feel inside, and what is driving you to do this. Work it so she can be your strongest ally.
I know I am coming off as a Black Hat Forum Dr. Phil... but I speak from experience. IF it is about a J-O-B to her than she may be secretly (or not so secretly) wishing for your failure so she can keep the household together (which is a GOOD thing... keeping the family from being homeless, not your failure

).
It is hard enough to work to start a business (there are alot of economic and social forces against you) without working way late at night, wishing you were sleeping, knowing your wife can not stand behind what you are doing and fighting that resentment.
On the other hand, it is alot easier to accomplish anything when your wife is there to cheer you on and support you. Nothing helps more when writing, then when I want to give up and a friendly hand sits on my shoulder, a familiar voice gives me some minor cheer leading and a loving smile asks me if she can get me a coffee or something. It can remind me why I am even trying any of this craziness, and gives me purpose and hope to succeed beyond my personal desire.
I don't have the skills that others have here... but I have been where you are . PM me if you need some emotional back-up
Next, here is some more concrete help for you. If you are going to accomplish this you will probably need some good time management skills (forgive me if you know this... I just know it helps).
I suggest one of two options (or both)
Listen to and read
Code:
Jimmy D. Brown's Six Figure Formula

You don't have to follow his exact methods, but he does an excellent job of showing you how to set up your work day schedule and plan out you week for the greatest effectiveness. It includes a number of printed schedule sheets to plan your time efficiently. Go through it and think about how you spend your time in relation to what actually gets the job done.
Second (though I'm sure many here would think it worthless) I got alot out of using
Code:
Mark Joyner's Simpleology course www.simpleology.com
to set up my goals and plan from a day to day basis. It really only takes 15-20 minutes to plan out a time saving successful day if you start with the end in mind.
Lastly... If you don't meet your goal... just because you don't reach your goal in 30 days, does not mean you failed. The most important goals are those we must bring ourselves up against over and over and over. Do not give up over a single loss. Don't forget, it is all a learning experience.
Let your new personal motto be:
DUM SPIRO, SPERO! ---
While I breathe, I hope!
Good Luck, God Bless!
