JOHN For my job, you need to do two or three years training usually while you are working with a company. You can't go to people's houses on your own and start fixing things without a qualification Now I have my own company, I usually work about 45 to 50 hours a week. It can be tiring. And, of course, you have to be careful, especially when you're tired. There are a lot of health and safety rules for example, you always have lo switch off the mains power. I heard of one guy who forgot and nearly died. Anyway there are good things, too you don't have to wear a suit or go to many meetings and I enjoy being my own boss
