The time, effort, and sacrifice you put into your work - what is the value of that? Can you quantify it in a dollar amount? Can you quantify it into any measurable unit?
I don't think you can.
Perhaps each of us have a currency that is unique to us. Perhaps that currency is a chapter of a story that we're hoping to tell ourselves about ourselves. If that's the case, then what's the actual story we're telling ourselves?

Knowing who you seek to serve and serving them - and not letting anything keep you from that cause - that kind of grit - that's the grit that matters.
That's living the good life.
