Sometimes it just is.
So often thankless and no one really knows how much energy you’ve put in. And if they do know, they still don’t understand.
In hindsight some of those details that you labored over didn’t really matter. But you couldn’t have known at the time, you were putting in the hard under-noticed never-noticed work.
You know what you’re aiming at but in the darkest moments you completely forget about the target and rely on the idea that you’ve trained yourself to keep moving toward it even in the pitch black.
Sometimes it’s work time. No pats on the back in sight. No time cards. No trophies. You’re just in it. You’re doing it. It won’t be like this forever so be glad for the hard work at hand.
