Froms and Minuses

The fault in my thought
Falls into froms and minuses.
All things, can I understand...
Save the most basic things
Such as distributive properties
Which creep into all my work
And make me unintelligible
For modern man.
It makes me unable to fold laundry
Or saw wood, or paint
Or draw, or do anything useful.
Beside this... Which, may be great
Or it may be yet another failure of mine.
Details never mattered much to me
Because my mind never was wont
To understand them... if too much of my mental
Aptitude is spent on a trivial thing
It triggers OCD, and I cannot now look
At the bigger picture. Vice versa.
My mind can only focus on one of two loci.
Either what's big and magnificent
Or small and petty. And I am naturally
More interested in bigger things...
Though I often fail at them because of the small.
