I can only answer this question based on my experience as a gambler of over 3 years. My formula for success in gambling is guided by the principles of which I use when gambling. It is the money that I can afford to lose that I use in gambling. If I win once, I am leaving. It is also the same when I lose too. I don't try to continue playing in both cases. All these ways helps to keep my loses down. I only take calculated risk and I am very loyal to the gambling site I play one. Not too much of an adventure seeker when it comes to trying new casinos if the ones I play at are perfoming well and treating their customers right.
