If someone is working harder mainly to fund their gambling then I have to respect their decision because it's their money. Maybe because I'm not in that category but it doesn't make sense to me that I have to be working harder to make more money because of gambling. I don't see gambling as an investment that it has to motivate me to work harder, I work harder because of my financial responsibilities which are quite much compared to my income. I cannot focus to work harder to fund gambling that I can lose the money to, I rather use small amounts to thrill myself in it.
However, working extra hard simply to finance gambling is not good at all; most often there is huge possibility that this path may lead to debt, job issues and other dangerous problems. Young bettors may suffer a large financial blow as they lean towards reallocating their savings & time. If you want that kick of betting then you can pile up capital separately for it, put a cap on bets 1 to 5% rules, put stricter loss & time limits on yourself & do not tap the capital for necessities.
