The fun will always be there even if you are losing money and you will only feel the sadness in you, the moment you step outside on casinos having no money at all same thing if you just playing online.

If you're too focus about the money you're making, having fun wont help you at all and many are playing with a lot of greed, the result is very bad for them. Just enjoy playing, spend the money you're willing to lose and you must have a strong emotionional control so you wont feel sad if you don't have money anymore.
