Hard work is a daily grind. My work is not physically demanding like many others, but it’s mentally grueling. I have a daily quota that is sometimes hard to reach for various reasons. When I reach that quota, it feels great because I have had to work really hard to get there. So yeah, I do feel fulfilled, but it can be frustrating and sometimes discouraging to get to where I need to be daily. Fulfillment can also come from other sources when work isn’t there for you.
