What matters is that I got my teeth into it.
I refused to be denied. So I dug in, researched the problem, and plowed on through. I ate an almost afterthought lunch, sat at my desk, and just ground through the problem. I would not be denied.
Other plans I had for my day fell clean off the table.
Eventually, I had a breakthrough. I figured it out. And then, implemented my change everywhere throughout the system. I wound up working late to get it just right.
It felt damn good.
