A tale of two days

To put it simply
Yesterday was a
disaster
And as these days do
It drug on, on
Faster and faster
And as these days are
I failed at all
I thought myself master

But!
Karma replied prompt
And luck was swapped

For today all
and everything worked well!
Again, I excelled
And once more the notes fell
into place
where the simplest person could tell
who I was
what I was
And where my soul dwells

Now excuse my manners for a time
For now I abandon all rhyme
And break the fourth wall

Tomorrow's the trouble
It terrifies me
Since Karma is callous
And Future's so grave
You! Never trust him
Or rely on his ways
For tomorrow determines
The rest of my life
