What's your take on this?
Are you saying that we should gamble with the money for our minor expenses because we can make profits from that money instead of using it for ourselves and families. I don't see think that's ideal because it means that you want to start gambling with an amount that you can afford to lose. Your win is not guaranteed because gambling is a game of luck.
It also means that you are taking gambling as your priority which is wrong. Have a gamble budget and stop gambling when you have exhausted your budget for that week until you have refilled it the next week.
If you have kids, or people living under your roof that it's your duty to take care of them, you can't avoid little expenses.
