Today is but tomorrow,
looking for a home;
but yesterday is lost,
in limbo it does roam.

In cyberspace somewhere,
it floats as in a dream;
and what you see today,
it isn't what it seems.

Time, it has no essence,
it's there, but it is not;
and goals that live today,
may someday die and rot.

Like visions of a nightmare,
too hard to comprehend;
the more that we do struggle,
the more it does not end.

Today is but tomorrow,
so grab life when you can;
for tomorrow may be nothing,
but one's unfinished plan.

David Lessard
