Even when the end of an action is dead certain, there is still some probability of risk.
We will not always know the outcome of our choices, but it is better to take reasonable risk than to be passive for the fear of failure.
Unless we take reasonable risk, opportunities available will not be fully utilised.
Do not let the attractive end of your action lure you to move without considering its dangers and implications.
Likewise, do not let the dangers and difficulties of your action discourage you from seeing the possible bright end.
Do not just take risk, take a reasonable and useful one.
