Some days it is a job, other days it isn't. Like many said it is what you make of it.

For me, most days are fun. Other days not so much. I am still getting used to the being a CA, so that continues to make it exciting.

Biggest factor for me: if I'm tired. If I'm well rested, I am enjoying myself all leg, every leg. If I'm tired, then each leg is a battle, and I can't wait to get to the hotel/home/sit to catch a nap.

Overall, I love the job, and would want to do any thing else...well except work a little less and get paid a little more, but in time that will come.
