Caution is not hesitation. To do or not to do. Because what ever may happen, you always do something - some action physical or mental.
When you mental processes are so trained, that these sift the unnecessary, avoidable risks. Out of your path of action. You know what is caution and what is inaction, born out of fear of what will happen if you fail. For mortals, let if be known that failures are stepping stones to success.
And cautions; you must be but only to recognize what risk is avoidable and realize that all actions however safe still carry with them some risk.
Death must come but let it come only once. For the one, who avoids action for fear of death, dies many times.
