if awareness is what you are after, a look into zen philosophy and training might be useful. zen emphasizes the concept of awareness and not judging about your preception or clinging to thoughts or emotions. i cannot claim to be a zen-buddhist but i have let myself be inspired by zen
there are a lot of methods in zen-teachings to develop and train awareness. a more ritualized version of what you have been doing would be zazen, sitting meditation. you might want to take a look at that.
what i like to do is go for a walk and just experience what is around me with as little thinking as possible. this is even harder than trying to refrain from thinking while sitting in quiet room because you encounter new things constantly and impressions fly at you all the time.
although the following is completely un-zen: it pays off. i started precieving little things i hardly ever noticed before. i got more aware of my surrounding, more concentrated on the moment and more confident, because i was in complete control. a feeling you can hardly describe with words and a striking experience at the same time. i strongly recommend you to look into zen-teachings if you want something like a all-day-mushin
