medical and life

when i become doctor longer and longer, i realized one thing. everything we practise in medical can use in our life practise. What i so called rules of universe. What is that?
When we advice people on operation /treatment which is high risk ,he can choose to accept it or reject it. In medical means conservative. Same rules can be practise in investment,if you take high risk investment, you can get high return. What is high risk, it is up to individual. For some people ,it is low risk.To another it is medium risk and for another it is high risk. It is up to individual. IN some patient,doctor see it as high risk , For him ,it is OK.When you proceed to his wish, he survives and for another choose a conservative method may dies in a year later. I called this "high risk ,high return " as rules of universe. Whatever you do in life, you face this choice everyday. You are the one who choose it, a right choice may make you promoted to another level and awrong choice make you suffered. The consequence depends on the big choice you make.
