I say, gee, that&#39;s great, if this works out then I&#39;ll get my name on the wall and maybe a small bonus. And if it doesn&#39;t then I&#39;ll get fired, I won&#39;t be able to pay the mortgage and my wife will divorce me. So whatever your question, the answer is no. To make it work without a huge reputation and network and existing relationships you need to rely on a lot of luck.</p><p>My general outlook on this is that if you read Horatio Alger, the general formula is luck, pluck, and virtue. Which is great, but what&#39;s even better is if you can minimize luck and make your bread-and-butter off just pluck and virtue. Then whatever luck comes your way is just icing on the cake.</p>',
