I only experience this when I was in my teenage days, back then the local internet cafe that I used to play or hang out was the main shop that the locals would go to play and have some bets on their games.
Back then I know the players who would have a match so I know how good they were compared to their enemy team so I am sure that they would win, so I borrowed a small amount of money from my friends and bet on that team to earn and the result was actually how I expect it to be.
But other than that I haven't tried to do it again, I would only borrow to invest or gamble if I am sure of that I would succeed.
A classic mentality when there's a local bet and you really trust the players that will be playing, you will going to try to bet with them even to the extent that you will barrow money as you really believe that they are in the good edge, lucky you as the outcome favor your side, as there are instances that a surprise upset take place. Leaving you with regret and a loan that you needed to pay with your allowance, need to adjust to make sure that you will be able to cover that loan money.
That's why it all boils down to discipline. If you aren't disciplined enough and you don't plan to become one anytime now or in the future, then don't engage in any gambling activities. Gambling requires not only money, but also enough mental capacity and discipline to handle all temptations that might come into your way the moment you start gambling. If you will fall for the urges and temptations everytime, then you are doomed to fall. It's not an easy process to be a responsible and disciplined person, but you have to be willing to in order to have a good gambling experience.
Gamblers shouldn't let their desire overtake their rational judgment because it will just cause trouble and headache. Additionally, it's more fun to play without thinking anything that might come at you and bother you in the middle of your game or your peaceful sleep at night knowing that you have no obligations to pay other than the necessities.
And most gamblers have lost discipline when they start gambling because the temptation of gambling can eliminate that discipline. And when the temptation gets bigger while they have lost many times, they decide to take loan money from other people to continue playing gambling. Even though borrowing money from other people cannot guarantee that they will get a win, it can cause more defeats. And they are not aware of it because they want to continue playing gambling and recover losses and get wins.
As long as we can think of gambling as entertainment, it means we are on the right track and won't try too hard in playing gambling. We can also play enough gambling by always paying attention to the duration of playing gambling so that we can adjust when it is time to stop gambling. That will prevent us from experiencing the many problems that might arise when playing gambling or after playing gambling.
Both points are valid, you'll lost your control and that discipline when you start engaging too much, the best way in treating this activity is always be aware of your action, make sure that you are still in control not to allow your emotion and greed to dominate you in making any decision regarding to your gambling activities.
