Stable mental health is the key; it can prevent addiction, and you are right; losses and greediness will kick in. If we can control it, we will not be losing big. My greediness, mostly when losing or winning, has also been my problem until now. I will tend to be aggressive in the long run to get back my losses, or if I feel lucky, I will mostly go all in, but in the end, I will lose a lot. Gambling is really based on luck, but it depends on the game. Those games in the casino are mostly luck-based games, but card games are combined, just as with sports betting.
many have lost their minds due to gambling addiction. even those who say they use the technique in playing, when they get out of control, the strategy will not affect the outcome. all that remains is to bet on an outcome of our luck. just run the bet until our money runs out. when finished then exit. no need to feel emotional and want to beat the bookies. just come back tomorrow with better luck.
If you are a player with self-conscious and aware in your gambling activity there's a possibility that you could control your gambling habit because not all the time its okay to follow your guts to play if you are aware with that you can easily identify to your self that you are already playing with your greediness or just playing for fun, some of them take playing gambling seriously and continuously playing as long as they see their current balance in their wallets. For me if you not feel well already or having a good mood in playing don't make it so you don't commit a bad decisions.
