I won $300 the first time I went to a casino (riverboat) when my sister took me back in 1993 (the day I turned 21,) and I was "hooked."
Then I proceeded to lose thousands in the ensuing years...
But, I finally started winning again....
Don't fret, it's just a bad streak you're going through, and it won't last forever!
I have a suggestion, though. It's something that I do from time to time if I can't seem to win anything. Take a break from gambling for awhile. A week, two weeks, a month, whatever it takes. I've gone as long as 3 months.
Not only will this save you some money, but it will also clear your head, so the next time you go to the casino, you won't be constantly thinking "I'm just going to lose again." For the most part, you're there to enjoy yourself, not to beat yourself up.
Believe me, you will have a much more enjoyable trip to the casino after taking a break from there for awhile!
