Note that the most important thing in gambling is bankroll management and finding value. What messes people up is poor bankroll management. Personally, I limit my bets to no more than 10 percent of my bankroll per day, I stop once that limit is reached. Also don't get discouraged if variance comes in and you have a losing day, week, month, etc. Value is value and it will catch up. Goodluck on your gambling journey.
Gambling oldies can throw in their 2 sats on this.
Bankroll management is really important but you also need self discipline on any other thing related to gambling so that you would learn something thru your experience and use it the way how you handle your gambling habits for sure if you manage all of risk especially managing it to make the chances to lose into low then with this we can be bullish on gambling. But also in reality its hard to achieve all of this so maybe we should focus to have fun instead stress ourselves on technical situations on gambling.
True to your word, discipline is key to gambling responsibly, because without it there'll be no control to the gambling habitat. Even when you have designed your bankroll management, without discipline to follow it through then it becomes a wasted effort. Because i know that gambling habit is enticing, the more you engage in it, you'll still have the urge to continue, even when common sense and all the self thoughts that you've given yourself is telling you to stop. At that point it's only self discipline that can apply the final brake and guide you to make the right decision.
To be involved in healthy gambling as OP has pointed out, requires discipline too, because without it the gambling becomes unhealthy. Generally i think that gambling should mainly be for having fun, not as a source of income, because of the risk that is involved. So how can a family man with responsibilities rely on a business that is based on luck to take care of his resoinsibilies, that sounds like irresponsible to me. Because if the individual experiences a big lose then what happens to the people that are dependant on him to survive.
