I agree. Discipline is the king here, if you have a big win or a big defeat, you should stop, consider the odds, and only then make your next move.
Definitely, if anyone masters this, then he/she can make better calls in gambling. Discipline is the key factor for everyone’s life in every profession. If you lack discipline and let your ego control you, then definitely you will make losses. You need to set small targets and need to achieve them daily. Double is a good amount to take a temporary pause and reward yourself with some luxury. If you take stress or greed and gamble, then definitely you will make losses.
Yup that's right and it is a fact that discipline is a key in anything we do in life as you said, because with discipline we will be slightly protected from various unwanted possibilities, such as losing the amount of winnings that you have previously obtained because you are caught up in greed, or losing large amounts of money because you do not act quickly to stop the scenario.
Setting a winning target I think is a bad idea, because there will always be times when bad days come in the sense that the game will not always be on your side, and with the idea of applying a target amount of winnings can make you challenged to continue your gambling session and it is dangerous when the results of the game are not on your side, so gamble as usual, not all winning amounts are in accordance with the target you have set, the point is when you succeed in achieving your first number of wins then that's the best time to stop and cash out.
