Will be happy to answer any questions you have if you describe me your practice and problems you're having via email (@ at my profile) - I've been practicing with several teachers / approaches and having this wider perspective is quite helpful when you reach any significant block.
I agree with the other poster that going to retreat is a great way to jumpstart the practice - often our daily life is causing of so much constant stress that we have to step out of it to even notice it. When we see it coming back in low doses, we're more likely to understand the patterns and what our personal mental antidote should look like.
BTW, there's a reddit group dedicated to his book, quite helpful.
By far the most amazing technology available for improving the mental condition of human beings. There is a reason people can super focus on things they enjoy, your emotions are the guide to what you choose to put attention on. When you have nervous, anxious or negative reactions to anything because of past experiences and preconceived notions you cannot fully concentrate or go in and out of flow states.
You can use EEG sensors to see the reactions your brain has to any task, concentrating, reading comprehension or math problems. With the technology you can see how your brain is reacting, how it "focuses", how "calm/alert" it is and if its "daydreaming" and my major problem which was "busy-brain". When you can see and hear feedback, you can "feel" how flow/concentration are constantly being interrupted. Eventually you can train your brain get into these flow states, get into them faster and under stress. I am only 25% through all my sessions and I have just begun to feel and see the magic that is flow. You conscious mind just shuts off and you just "do it".
This is makes a huge impact of meditation as well, you can sit still and focus on your breath, but I find it far more effective to focus on your feelings. I try to guide them and bring them towards courage, passion, love and appreciation. Which brings them closer towards inspiration and happiness and a better functioning mind.
This is all just from physically/emotional painful experiences. So I guess just take with a grain of salt. But it's made huge differences in my physical/mental well-being.
Even perfectly 'healthy' human being will still have the layer of basic fear, whenever what he considers to be his core identity is under threat. In meditation everyone at some point needs to face it. So I wouldn't take what you're saying with a grain of salt - on the contrary, you may now have much greater clarity, as you had to be much more systematic and determined in your training.
I'd also love to hear more details about the tools you used. Are these consumer grade or hospital type of equipment?
Having the patience to mediate for the entire year without results pretty much dooms you to success.
