    This year has been a busy year of travelling for me, and the end of the year is no exception. I booked an early morning flight so I had to get up at 4:30 am to get to the airport. The thought of such an early flight made me not very happy, but then I started to think about the people who would make that early journey possible for me: my taxi driver, check-in agent, security staff, gate agents, flight crew, etc. They all do their jobs at an early hour so I can get to my destination safely, often for very little money.

When that trip came, I realized I had a choice: I could be angry about having to take an early flight, finally showing my anger to everyone I see. Or I could choose to be grateful to this modern machine of safe air travel and the people who made it possible. Just thinking about the latter choice got my mind working about how I could show my thanks, and I decided to do a little “experiment”: what if I got a little gift for every worker I met my journey? How many gifts would I end up giving out?

Then I started to think about what kind of gift would be good for such an experiment.

The payback from this experiment started immediately. For the first time in years I actually looked forward to getting up at 4:30 am! I ended up giving a gift cards to my taxi driver, airport security agent, two gate agents, and four fight attendants, and all of them said thank you and smiled sweetly. And, instead of arriving tired and sad after four hours of sleep and a long flight, I was excited and happy to share my story.
