    I wandered into the small store where I usually buy milk, when the store owner received a call from a customer. The customer and his wife had shopped there several months earlier. He noticed that his wife really liked one thing in the store, so he wanted to buy it as a surprise.

    But the customer was in Tennessee, far away from the store which was in Maine. What was more, he had been to the store several months earlier, and it was difficult to believe that the store owner would remember him, or what he was looking for.

    The store owner took a few close-up photos with her camera, and e-mailed them to the customer on the computer. The customer looked at the photos, and decided which one he wanted. They talked and discussed a price over the phone. She took care of the credit card transaction (交易) online, and promised the gift would be shipped out that afternoon.

    The store owner was really smart. She was willing to push herself to find new ways to make the transaction actually happen. And it did work. However, it was the first time she had ever done it.

    I was amazed that the store owner discovered a creative solution that could lead to a new way of doing business. I was impressed by what she did—so easily, but how difficult it is for many of us to make that leap(飞跃). I'm not just talking about technology, but about learning how to adapt to change. Most people hate or fear change unless they get to know exactly what change needs to be made. However, we should realize that challenge and opportunity go hand in hand.
