Grind
Heart tends to break my chest in these types of interactions. I just want to work. When skill and effort can only take you so far, what else can you do? Grind.
I've often thought, re-thought, and pondered once more I can pursue something that interests me. Often I achieve such pursuits, but it never settles the constant thump that grows louder as I continue at a neck breaking speed. That's grind.
If I can bestow one thing to my children it's this: Grind. Keep grinding. When you're tired, rest. Then grind again. The dreams can be achieved, we just have to grind until we do.
