I've been experiencing this feeling lately - on two occasions when we were out to lunch, I could actually stop myself from thinking about the chores pending at home, things I had to work on online, and generally what's-next thoughts... . I actually managed it! after the lunch, I realized I actually had had no thoughts in my head other than thoughts about the food and the company; as if there was nothing for me to do, other than just have lunch. How to explain the feeling of liberation.... it was a wonderful freeing kind of feeling.
Now, since that was such an enjoyable feeling, that is what i am mightily going to strive for while doing each of my tasks.
