It's a mix of things. My grandmother brought me up to be a hard worker from a very young age, so some of it's just an ingrained habit. I looked for her approval and to hear she was proud of me for a long time, and working hard was the only way I knew how to get it.
But, now especially, I love what I do. I love the people I work with. I love that I get to give people a fun experience and somewhere to get away even if it's just for the night.
