Q & A: Listen to Scott's answer on the question, "I ran a business for about 18 months and then shelved it because I realised I didn't really enjoy the type of business I was in and also, the margins weren't quite there. I have gone back to full time employment since, but am looking to relaunch another business soon. I am stuck because I don't know what business I should start. Should it be in education, retail etc. And I am looking to start something part time whilst I still have cash flow from my regular job. Can you assist me in working out how to identify a profitable niche?"
