I used to get frustrated coming here, to possibly the largest convention center on the planet or even the solar system. I'd walk all day, my feet would be sore and I'd generally be both exhausted and grumpy.
Then, I got a FitbIt. My life changed. I walk many miles a day and enjoy it! Now, I actually looked forward to coming here and walking all day! I get a zillion steps and it's part of my job! I'm a fan!
