Every business venture starts with an idea.
A business does not run solely on money, it runs on passion. You should enjoy your concept and be excited enough to relay your feelings to your market. You can survive in business without a large bank account - but unless your passionate about your business, no amount of money will make it sell. Your concept doesn't need to be a freshly thought idea - but could be an improvement to an existing market. There are all kinds of new businesses that have tried and failed.
