You seems to be contradicting your own words there. You are stating that you decided to quit but on the other hand, you are looking for a good tipster for sports betting. Point is once you are a gambler then you will be hard to control your greed and emotions in winning more .You might say that you want to stop but deep down you will always want to earn more from gambling
