I think everyone starts thinking about the final outcome, whether that is doubling your money or winning against huge odds in the lottery. I rarely place any bets and probably buy lottery tickets the most, but it is nice to dream of leaving your job and being set forever by swapping a cheap ticket for millions. It can actually give you a lot of hope in life, even though the chances of winning are infinitesimally small, and bring a bit of happiness at the possibility. For football bets or similar however, it does add a bit more spice to watching the game and makes me feel more involved - especially when a group of friends all have different bets placed as you watch it.
Oh, yes! How I understand you perfectly about adding thrills when you personally place a bet on a match. You watch it completely differently than without a bet. More worries, emotions and adrenaline. It turns out that betting is not such a bad thing ) You just have to be extremely careful and attentive, so that disappointment does not come later instead of happy memories.
