Gambling is never a life or death situation, where you'll feel like making reckless decisions on your games is the only option you have. Every individual that is into gambling aims at winning; for me, that's enough to guide me against taking unnecessary risk.

Also, I don't play casino games, but I don't see anything wrong with them either. Time is a very important factor that decides what I do, and for how long I can keep doing it -- that's also another way to avoid getting into the game at the wrong time. Someone said "learning lessons from other people's previous experiences" is also a way to avoid making silly mistakes, I agree with him.
