Your first argument is not realy valid. Did he learn how to do it while working in box and succeeded in it? I have started companies and worked as contractor in domains I didn&#x27;t  really have  experience in and actually knew if I could succeed. Lucky I did and yes now I have prove for myself and more important to others to validate this. So in conclusion I learned how to do it and was succesful and I validated it.<p>On the down payment don&#x27;t really have an argument there as SF and Europe differ a lot on pay and housing costs.
