We have had a lot of practice. All life long. Nay for many births.
Of constantly worrying or brooding or imagining.
Watch a movie. And you will constantly say oh no! Or that’s good. Or I wonder what is next ? Or this is what I would have done. Etc !
But that’s what we call enjoyment.
Now the habit takes a permanent hold. And as we grow older we try not to worry or think of our future or look forward to things in life – we get stuck. We just can’t stop thinking !
Sad. It takes a lot of practice to get rid of this trait. Vivekananda called it painting pictures.
But it can be done.
