单项选择题
　Ron was an engineer. He planned a change and tried the new job of teaching kids how to swim. Ron’s easy manner soon made him a full-time employee at the swim school.
Now, the 40 hours he works a week takes in weekends, early mornings and late afternoons. He earned around 25% less than he did in engineering. But, at 49, he says he has never been happier. “I’ve had a drop in pay, but I’ve cut back on spending, too. I seldom drive to work so don’t have to pay as much for petrol（汽油）. I don’t drink as much. I go walking in my lunch break and I’ve lost 20 kilos. I love going to work. The whole family is a lot happier.”
When one of his brothers called, offering to help him find “a real job”, he answered, “I don’t care. I know what I’m doing is good.”
He admits it was fearful making such a big change when there was the mortgage（分期付款）to pay and kids to clothe and feed, but in the end he feels it is a simple choice. “If you’re in a job you don’t like, get out. Money’s not everything. If you don’t like it, change－find something you’re going to be happy with.”
