That's right you mentioned some of the points above, but building character as a professional gambler is not easy even though we already know the general things as mentioned in thread or at several other threads, we will always be faced with emotional when gambling at casino. Except spoortsbook, because spoortsbook requires analysis with some notes or news that we have to think about in make a bet.
Controlling our emotions when it comes to our money is something that is always difficult to do and we see another example of this when it comes to trading, and activity that while very different from gambling also includes putting your money at risk.
When it comes to trading you are supposed to always remain in perfect control of your emotions and trade just based on what the charts are indicating you, however this is incredibly difficult and once people begin trading with their emotions they face huge losses, in a process which is very similar to what happens when people gamble and lose the control over their emotions.
Yes, this is something clear, controlling emotions sounds very easy, but in reality it is very difficult to do it, since sometimes one says that it is controlled but sometimes it is not, this is a bit difficult, it is like in trading, however I consider that when a person is a professional in gambling or trading, he handles an amount equal to or greater than $1M, because it is no longer anything, a movement can lead to a great profit or a great loss, But I know that in the world there are people who manage those amounts of money, that is where I consider them professionals, for me that is the main criterion.
