If you try to pay attention all day long, you will end up exhausted. If you are not trying to pay attention, nor suppress it, it will go on its own. The problem here lies is the delusion that knowing is contrived and we have to put effort into it. Knowing don't have to be contrive, is not contrived, and cannot be contrived. Don't try to change, just be mindful. But to be mindful, you don't have to do anything, as you are the mindfulness itself. Just be, without trying to be this or that. And don't worry, there will still be understanding, action, engagement. You will go to work, or school, eat, sleep... in the same way, just without the burden of responsibility. Sensations may arise of you not understanding what is going on, but you will see that everything goes fine anyways. Most of the time it will go much better then before. People lack this self trust and this fear it understandable. I had such a sensation when I was in my working place. I am IT specialist, so a looooot of understanding is required. To my surprise, although I had no idea what I was talking about (it just came out of my mouth without the need of contriving it) everyone was amazed how technically precise I was.
This momentary "mindfulness" that jumps in from time to time and tries to control and direct, is the only moment of delusion.
Say what you think about me here.
