You've said it all, friend, gambling is risky, and the higher the risk, the higher your gain, vice versa, so the choice is left to the gambler. All I am mainly particular about while gambling that are related to the subject matter are: 1. My chance in each bet, and 2. The management of my gambling risk. The consciousness of the two surely helps me keep my sanity and avoid financial ruin.

Gamblers should also ensure they do it without being desperate.
