Myth #8: I need $5 million to start my business

Reality: Unless you're building hardware (in which case you should definitely rethink what you're doing) you most likely don't need any startup capital at all. Paul Graham has written extensively about this so I won't belabor it too much, except to say this: you don't need much startup capital, but what you do need is a willingness to work your buns off. You have to bring your brilliant idea to fruition yourself; no one else will do it for you, and no one will give you the money to hire someone to do it for you. The reason is very simple: if you don't believe in the commercial potential of your idea enough to give up your evenings and weekends to own a bigger chunk of it, why should anyone else believe in it enough to put their hard-earned money at risk?
