Happy and motivated employees usually have something that they take pride in. What is your point of pride in your current workplace?
"In my current job I am most proud of the environment that I have created with my team since taking over as crew lead. We have fun and get the job done at the same time. Productivity has increased and turnover has declined steadily."
"I'm most proud of how well I take care of my passengers. A lot of them find me memorable. It's always a pleasant surprise when a passenger says hi to me and tells me that they remember me from their trip to such-and-such place. It tells me that I'm consistently doing a great job."
