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 earns 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 i oh", 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. "
What is Ron´s new job like?

A Well-paid.

B Interesting.

C Easy to do.

D No free time.
