excessive gambling. It is better to gamble only in spare time, so it can keep us from addiction. Initially, we were addicted to too much time
playing gambling, so without realizing it we were getting addicted to gambling. Managing finances and time is quite effective in keeping us from
gambling addiction.
Actually, that's no necessary if you have a lot of time to gamble, what you need to do is just be discipline all the time that you will always in control. That means you don't gamble above your limit, and you don't lose that control that would result in you chasing your losses. I experience that many times in my life as a gambler, so I know it's one of the biggest mistakes of the gamblers and the result is not always good.
I think this is a dangerous approach because some people have a lot of free time, especially these days during lockdowns and stuff. But even without lockdowns everyone gets days off, and it doesn't mean spending 10+ hours on gambling during those days is OK. Same goes for money: if you received a huge bonus, don't think you can spend more on gambling now than before. Spend only what you can afford to lose on normal days on average.
