If the only new thing we have to offer is an improved version of the past, then today can only be inferior to yesterday. Hypnotized by images of the past, we risk losing all capacity for creative change.
What you've done becomes the judge of what you're going to do especially in other people's minds. When you're traveling, you are what you are. People don't have your past to hold against you. No yesterdays on the road.
We do NOT know the past in chronological sequence. It may be convenient to lay it out anesthetized on the table with dates pasted on here and there, but what we know we know by ripples and spirals eddying out from us and from our own time.
Who so desireth to know what will be hereafter, let him think of what is past, for the world hath ever been in a circular revolution; whatsoever is now, was heretofore; and things past or present, are no other than such as shall be again: Redit orbis in orbem.
I tell you the past is a bucket of ashes, so live not in your yesterdays, no just for tomorrow, but in the here and now. Keep moving and forget the post mortems; and remember, no one can get the jump on the future.
