Like a mirror, your outer reality reflects what is going on inside of you. Your external circumstances will only change when your internal changes. You really do have to "be the change you want to see in the world".
I understand your frustration, I really do. But this frustration will only increase if you keep focusing on the external circumstances at the expense of your internal dialogue.
An example from my recent work with this (I know it's not directly about happiness, but the process is the same - hopefully using an example from something slightly more concrete will help...): I'm writing a book. A couple of weeks ago I hit a dead end. No ideas, no inspiration. Okay, maybe this is a bit about happiness (or lack of), because I was miserable, with a capital M
After being in this state for about a week, I started listening to myself... "I am stuck", "I am so frustrated", "I have no idea where to go next", "I just don't know what to do"... Since the universe just gives us back what we put out, guess what I was getting? Yip, stuckness, frustration, no ideas. Nada. So, I thought I'd start saying something different, even though I didn't really feel 100% there: "I am open to inspiration", "I am receiving inspiration", "I am grateful for ideas that come to me"... Later that day, I had my first creative thought of the week (ok, to LoA people, I know... all my thoughts that week were creative, this was just the first positive one
). But you get the point - I changed my internal dialogue, even though it felt like a bit of a leap, and my external reality started to change around me. I've kept up the more positive dialogue and the ideas keep coming.
It does feel like a leap when you don't currently see yourself where you want to be. That's why you have to start with process type stuff, something that feels credible to you at this point in time, like really focusing on the few things you mention that you are grateful for. And, you also have to have a bit of faith... leap and the net will appear, I promise
You have the most control over your own internal dialogue - do one of Steve's 30 day experiments perhaps, and see where it leads you...?
(PS: I know it's all related, but I've never personally used EFT and NLP...)
