I never find anything positive towards gambling because gambling is just for time not for money making the machine. I never consider gambling is another source of income because the chances of making money are very difficult and sometimes addiction will also kill us on our expenses.
You'll never find success to gambling because you already said it.
And don't go too far with it if you have decide not to create it as a source of income because it shouldn't be. Its not worth to try because base on my personal experience I wouldn't really going to go through with it anymore and I'm done finding my success in gambling.
