For them it's about your addiction, and that's what brings in more money, and I am here to announce to you that time fixation is also a good way in gambling, spending 20 minutes in casino a day is better than someone who spend 1 hour.
1. Have a amount limit you can risk on gambling every week.
2. Choose your favourite day in a week for gambling.
3. Have a time count down when gambling, to avoid spending too much time.
An individual can do all you wrote and still not make profits from gambling, gambling works in different ways for different individual but been disciplined and having self control is a good way to make yourself not to get addicted to gambling but it wouldn't make you profits. Having an amount limit will not making you successful but it'll make you not get addicted to gambling as when your limit is crossed you'll have to stop gambling which will make you not become an addicted gambler.
Having a favourite day mightn't work for all individuals as some individuals will be more successful when they gamble based on how they're feeling for the day. There are days when I'm feelings very lucky and I just go to the casino to gamble and it turns out to be a good decisions as I make alot of profits. Having a special day mightn't give you the profits you're expecting as gambling doesn't have a path.
