Opening up your own small business can bring a host of benefits,more freedom, flexible working hours, more career opportunities and many of your dreams realised. But the sad truth is, there are more closures than start ups every year. In the US, 95 out of 100 fail within the first five years.The good news is that statistics show small businesses started by women have a greater chance of success - experts think it's because women plan more, and take things step by step. A recent study on factors influencing career success conducted by Accenture, a global management consulting company, found that women feel juggling family support, planning and ambition is important for them to advance in their careers.Why is planning important? Because we all know a great business starts with a great idea. But there's so much more. Often, would be entrepreneurs get so excited about their idea that they forget to find out whether it's viable or not.
