"Those who cannot remember the past
are condemned to repeat it.
Look not mournfully into the past.
It comes not back again.
Wisely improve the present.
It is thine.
Go forth to meet the shadowy future, without fear.
We can draw lessons from the past,
but we cannot live in it.
Live neither in the past nor in the future,
but let each day's work absorb your entire energies,
and satisfy your widest ambition.
Events in the past may be
roughly divided into those which probably never happened
and those which do not matter.
I don't think of the past.
The only thing that matters is the everlasting present."
