I have been in the habit of cultivating All Day Awareness for many years now. It began with a technique to facilitate Lucid Dreams and I practiced it vigorously for many month. I noticed that it became a habit. I was doing it for a great length of time every day without much effort. And even though I did not keep up the practice at that level in the recent past, I still notice a high degree of Awareness for the present moment. It is grounded in my direct sensory experience. And I am pulled back to it at regular intervals without conscious effort or a reminder.
This has recently led to a profound insight. Being highly conscious of ones direct experience at regular intervals does provide a lot of opportunities to asses and reflect ones actions and situations in general. This fleeting experience of the emotional state in combination with a grounded presence often reveals raw and honest truth!
I discover emotional triggers early on in their chain of reaction. It teaches how the brain constructs it's own problems into the world. I also learn very early if something is going wrong in general in my life. Or if my actions really reflect my true inner values.
This can be difficult in the moment, when you have to face every problem. On the positive side this gives me the opportunity to stop problems before they become to big to handle. And ultimately I believe it is easier for me to become fulfilled with what I do in life through this practice. Avoiding the development of serious life-issues, negative habits and being able to listen to the guiding inner voice are among the greatest benefits of practicing All Day Awareness long-term.
To start the practice I recommend setting an alarm on your phone at regular intervals. You can find apps in your app-store that do this by searching for "reality check" for example.
In addition to a daily meditation practice this can facilitate your personal development greatly. But be warned that this might force you to drastically change your life. Even if you right now think this might not do much for you and you are comfortable with what you are doing most of the time. Any action that is not fully aligned with your true values will be openly revealed by this technique. And if you stay aware you can not act against your own believes for very long. You can only do that by listening to and being absorbed in the inner voice that justifies the action while you are acting it out. And then you are most likely not fully present.
Full Awareness of the present moment is a good guidance and probably the best we have access to.
