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.
