I have read Eckhart Tolle's, The Power of Now.
I saw value in the idea that when your focus is completely present, there is quality in what you do.
I've applied this and it works for me, where I used to often be distracted by excessive thinking (concerning past and future) that prevented me from observing a situation clearly.
My concern is that things are running smoothly for me right now and that, should I be required to remain focused, present and out of the absorption of distracting thoughts / ego engagement to provide quality responses in situations of panic, arguments and so on, that it would be extremely difficult to have such discipline.
What method has worked for you to keep your focus completely in the present moment without your attention going into whirlpools of seizing thought?
