No one should gamble because they are looking for ways to to make money and choose gambling. What that will end it is addiction and further loss of money.
This is the secret many people have not known... the moment you have the mindset that you want to make money from gambling and you add some kind of desperation, hell will be let loosed and the cycle of doom will set in. On the other hand, when you are playing for fun and do not desperately need the money, the winning will flow naturally over little efforts. I don't know why gambling work that way, but I am sure it has to do with psychology.
The best way gamblers can be disciplined is to only have 5% of monthly income for gambling and it should not surpass that amount. This has been the strategy that has been helping me since long time ago till now.
This is risk management in practice. It requires a great deal of courage and discipline to implement but if fully implemented, it will lead to a kind of balanced psychology, peace of mind and better performance. Many people missed it in gambling when they play without setting the targets and calculating their acceptable risk exposure before even getting started.
