In my opinion, humans are somehow like trees. The roots represent the past, the trunk the moment and the crown the future. Only if all 3 components of the tree are in balance, life is healthful.
Time is next to nature probably the most valuable asset that reality has to offer.
But what is time ?
We humans suffer from a curse of unknowingness.
If we cant deny time, we should learn from it.
Through the moment the future can be shaped and the past can be consolidated.
