When I was 9 years old, I loved to go fishing with my dad. He could catch many fish while I couldn't catch (something). I felt so surprised that I kept asking him why. He (answer), "Son, if you want to catch a fish, you have to think like a fish." I didn't know how to think like a fish. I was (worry), as I'm not a fish.
The problem troubled me for many years. As I grew much (old), I began to know what my dad really meant. So I read some (book) on fishing and joined the fishing club. I learned a lot about fish. For example, fish prefer shallow (浅的) water the shallow water is warmer. Gradually, I was good fishing and catching them. When I grew up, I entered the business world. I (tell) by my boss, "We all need to think like salespeople." But I didn't think so. My dad never said, "You need to think like a fisherman." I tried (provide) the best service for customers. I understood that what we all need is to think more like customers. It's really not easy job.
