But that was yesterday

A poem I wrote.

I was trying to doing something that would never work,
and realized that my efforts were shirked;
but that was yesterday.

I couldn't find a reason to get out of bed,
I tripped on my mantle and hit my obtuse head;
but that was yesterday.

Could there be a yesterday such a far off place
of forgotten dreams and foreign tastes,
and though all of it seems so much like today;
it was in fact yesterday.
