What is Time?

What is time? An illusion of existence.  I believe in each... time past, present and future coexist.  Life turning on an axis, the time that has passed comes back.  Inside each of the species there's much of an hourglass. Like each, I have a past, a present, a future, and am constantly projecting myself onto the future. At the same time I remember the past and experience the present, even though my present really never exists.  What’s my present is my extremely recent past, as the present is an instant that tends to be infinite until thought makes it not. Time is my only true asset and as long as I have it I am rich.  Aware in Its Presence, Infinitely so.
