I have had different worse losses, first was when I started gambling newly and believed that the way some friends were winning is also how I can win, but when I lost the money I should have used to purchase my needs, I just felt frustrated, there was another incident of when I was still in the university, I used my last money to stake on a game and I lost the money. It was painful.
These things are what we shouldn't do as a gambler because whenever you think of how much you want to win and how big is the money you wouldn't be that smart enough to know that you have two chances, that is either you win or you lose while using your money meant for something more better to gamble. It's always advisable to all gamblers to use money that are being attached to something meaningful for gambling because sometimes the money the is meant for important thing could be lose while gambling.
That's it, it's not advisable for someone to take gambling as a source of income and it's not also smart for someone to stake with the money they can not afford to lose or with the money that was not meant to be used for gambling. The mistake some people do is to staked with the money that was supposed to be used for other important needs, they spend it on gambling, thinking they can multiply it but at the end, they lose it and start to regret.
