1 rule = allawys think about winning and nothing but winning
2 rule = never get so greedy
Your 2 rules are both contradicting to each other. Rule 1 says is like that just always think with profit nothing but profit and that is making gamblers more greedy enough. And by making those aims to follow, I guess that isn't going to make you a productive one and that's going to be a good strategy except rule number 2 that we mustn't be greedy.
