I like to think of my gambling wins as an income boost and depending on the amount, I always prefer using it to solve a particular issue or purchase a need that would always remind me of the winning.
Let's hear from you, how do you think gambling winnings should be spent?
That's the right thing to do, but never think that you can make gambling a part of your job that you will do often to augment your income, because it will do the opposite, draining your finances.
We should not think that gambling is income generation, because casinos are not meant to be like that; only the casino operators make a continuous profit from the casino, just be contented with your winning, and play with no expectation.
