With every dream we have,
there is a dozen we leave behind.
In this world, there is no space.
There is no place,
for things Impossible to achieve,
and we forget them as time goes on,
along with our missed chances.
We do what we can;
with whatever skills we’ve got,
hoping it is enough,
to see us through.
Maybe it is and maybe it isn’t.
It is something we will never know.
