If you focus on how much you will lose, that means you will focus on how to manage your money that you are using to gamble, having gambling budget and not using more than what you can afford to lose. So this makes me not to completely agrees with you. It is good to focus on how you can lose for you not to fall victim of gambling loss.
When you focus on how much you are going to lose in gambling, it means you are doing nothing but management of your deposit and when you manage your deposit, you are indirectly trying to maximize profits; how about that? As a gambler, you should never sleep on your deposit and always check well before you make that move, you should have limit to amount you want to bet and maximum accumulated bets or multiplier you want to use. Just because Mr T win with 200 oods or multiplier doesn't mean you should do the same, you will lose if you copy another person.
In as much as it's good to focus on the loss, you are already making sure of good profits, with this strategy you are indirectly gambling responsibly and it will help you reduce your loses and even plan ahead of what game is good for you because if you play one and it didn't work, you wouldn't try it next time or when you try a method and it didn't work, you will avoid such mistake next time.
