We believe that tomorrow will be come because we were experienced in yesterday.
If we don't remember yesterday and never see somebody awaken from sleeping. We may not (or may) believe yesterday.

Tomorrow is the future. Yesterday was the pass. But we need the present to practice mind fulness.

The present show that the mind was rebirth every moment. Like your post
I had an ah-hah moment then. mean that moment your mind rebirth to a new mind. And now your mind is not the same as "ah-hah" mind.
It's rebirth every moment.
