The hope that one day luck will permit you to experience winning huge amount of profits, a very common thing in each gambler who has the desire to win. Not easy, but we never know when luck will back us up. Just know your limitations and avoid exceeding from overspending while playing.
Gambling is a combination of entertainment and a potential money maker only if you have that luck.
It's really amazing if one day you are sharing your experienced having that chance winning the jackpot!
If you have been gambling for a long time then I think you have experienced a winning moment and this is why you keep on coming back to gamble again. It is not easy to tell when will our luck come back but did you know, in Chinese culture they use gambling as a way to test their luck?
I think that if they win, they'll then think that they are lucky so they will start doing something's outside gambling like opening up a business. For us regulars, it's not bad to gamble but as you said, we shall stick to our limits. I know there's a time where we can't get enough but if this happens then do something like what @Biscutard said which could distract yourself.
