Several years back i lost over £100k trying to be the next big thing. It can happen really quick too. Put your prices up and by a good margin, you wont believe how much people will pay if they want you to do their job. Dont take a financial risk until you can afford to do so, and when you can be meticulous. Also you have to accept that most blokes who work for you wont be as good as you and certainly dont care anywhere near as much as you either, thats life.
