I get a nice high with the possibility of winning

Keep it up if that's what you are feeling well who knows you might ending up big you will not know unless you try but gambling is risky better be careful in wasting money that much.
People tend to go for options where they can quickly make a lot of cash. And gambling provides them this option.
They play and keep playing hoping they will win the jackpot eventually.
Yup! Playing gambling provides that option in winning instant money for you but it hasa negative draw back when you lose and that can be irritating and can lead to frustration so you need to just bet small amount of money so not all money you have could be lost.
