Do you take responsibility for your losses, or do you play blame game?
One sign of maturity is taking responsibility for your actions. Individuals who still play the blame games are irresponsible gamblers who should not be gambling in the first place, and that is a sign of immaturity. These kinds of people are the exact kind of persons that you should be cautious when introducing them to an opportunity, not just gambling, even if they feel or have an interest originally, because at the end of the day they may end up blaming you for whatever the outcome of the action that they took with their own hands.
You are right about this not being able to accept responsibility of our actions is childish and such person has a long way to go and when it comes to introducing anyone to an opportunity it is best you throw it at them at a sight for them to make their own personal decisions after the risk and the potential benefits has been made known to them, gambling is never and should never be done by force, it is very simple game where if you can't risk it don't gamble it so you don't blame anyone at the end when things didn't work as expected
, it is only natural to think and do anything in the direction taken responsibility for whatever becomes of the outcome.
