Op this is a good list that would be adhered to in a utopian society. Having said this, I think it should be "Things to consider" and not "Things to obey". Obedience here doesn't guarantee "success in gambling". The fact is that not everyone has the luxury of gambling for entertainment. For some people is another source of income. So they take it very seriously. I am not referring to those who turn to gambling as a coping mechanism from life's challenges.
