As echoed by everyone else, don't risk your family and family finances. Look for B2B ideas not B2C. Don't focus on big ideas, I read a dry old book a long time ago, called the 'wealth of nations'. The key bit that stood out for me was an observation that the workers in the looms and mills built machines to improct things for them, and then capitialsed on it (where their landowners/lords etc supported them) With that in mind, the best comment I ever read was 'every spreadsheet tool you see in a business is an app crying out to be made'. Look around the company and business area you already work for/in. You have an advantage in knowledge of their business and where the shortcomings are. You will need to tread carefully as you don't want to loose your idea to a byline in your employment contract.
