I learned a lesson in marketing from a man who bought an old boat, a trailer, and a motor from me. "Thanks," he said as he loaded them up. "I'm planning to resell them."
Good luck, I thought. I had been trying to get rid of them for months. But when I ran into him a few weeks later, he'd sold everything.
"How did you manage that?" I marveled.
"I took out an ad: 'Heavy-duty boat trailer with free boat.' When the buyer came to get it, I asked if he had a motor. He said no. I told him I happened to have one in my garage. Bought that, too."

I'd been working on my business degree for about a year when I finally got to take a popular finance course. I went to the bookstore to buy the textbook and was shocked to find out it would cost me $125. I asked how much it was worth if I sold it back at the end of the semester.
An older, tired-looking dog wandered into my yard. I could tell from his collar and well-fed belly that he had a home and was well taken care of. He calmly came over to me, I gave him a few pats on his head. Then he followed me into my house, slowly walked down the hall, curled up in the corner and fell asleep.
