No risk, no reward and this is gambling. The consequences are permanently there and there is no way to alter it. Losing it will make him think that he has to do it again.
That is why we must know and understand exactly how to manage the risks in order to minimize the risks of losing.
If we have known about the risks, but we don't learn yet, only follow somebody else, not even trying to learn from its experience in gambling, the risks will be higher.
You are right that no risks, no rewards. If we don't take the risks, we may not get what we want. But if we want to take the risks, we must know how to minimize the risk, at least, how to avoid the condition in that risks.
