My cylinders are primed; how to ignite the engine??

Ok so I feel silly even asking this, considering the hours I've spent on here reading everyone's amazing techniques on motivation, happiness, and the like. I'm surely asking a question that gets asked over and over again, in fact, I've seen it asked, but here I am....

In short, I feel like I am READY. I am SO READY. If I were translated into a pilot's takeoff procedures, I feel as though I have most of the correct switches flipped and am ready for the overseas flight to big things and achieving my dreams. I just have not been able to find an effective method to really light the fire beneath me. The embers are burning hot, and I can't light the fire!!

I will include this, because maybe someone can help me with direction. I am in the very unfortunate position of being a 29 year-old with nothing more than a H.S. Diploma, no post-education, and a lengthy record. It is all more-or-less related to my addictive personality, and poor decision making. My fault, and it is far in the past, but it still exists. I have always known that I would love to WRITE for a living, and when anyone has ever asked me what I think I might still want to do, that has been my standby answer; writing.

I've never known specifically how, or what, but just that I would love to share my thoughts and make a living doing it. So...blog perhaps? And the first thing I think of is that it requires consistency that I don't think I'll be able to devote. I get sidetracked too quickly, thinking of different means that would be 'easier.' I guess it would seem I have developed a lot of mental flaws or ways of thinking that simply don't help me light that fire. Subconscious or not, I am so tired of not being able to buckle down and focus on one thing, and it's probably related to not truly knowing what that one thing should be.

I'll try to wrap this up... I quit drinking 2 years ago, and the one thing that I have 'expertise' on, is treatment, addiction, psychology, etc... The criminal mind, so to speak. There are so many cookie cutter treatment programs and COUNSELORS especially that are simply offering help by doing what some book told them to do. It's not real experience and it doesn't help anyone. I want to be able to help....but I don't want to be a treatment counselor. I'd love to somehow counsel or earn a living doing something related to this. Offering advice to people; detailed advice as opposed to the free advice that I'd absolutely offer to anyone that asked for my help relating to their addictions or struggles with depression.

So yeah........... I'm asking for someone else to light my fire, lol. I guess I'm doing it wrong. I need to light my own fire. JUST HOW?! How do I close my laptop, or in this case maybe keep my laptop open, and start doing something with my desires? I can only read so much before I have to take action, right? I just feel like I have most of the ingredients to make my dreams come true, but I can't pinpoint the exact reason I won't start taking off. I don't know how. I want to learn.
