When you accept what is, you are grateful for whatever situation arises.
Time isn't precious at all, because it is an illusion.
Nothing that was real ever died, only names, forms, and illusions.
You cannot be both unhappy, and fully present in the Now.
Time is the horizontal dimension of life, the surface layer of reality. Then there is the vertical dimension of depth, accessible only through the portal of the present moment.
When you say, 'I enjoy doing this or that', it is really a misperception. It makes it appear that the joy comes from what you do, but that is not the case. Joy does not come from what you do, it flows into what you do and thus into this world from deep within you.
