No it's not easy, if it's easy, I should have successfully convinced many gamblers to stop being addicts.
Everyone knows that smoking is harmful, and excess weight causes health problems, but there are a huge number of people who cannot quit smoking or lose weight. What do you think makes a person become a responsible player and why is it difficult for many?
Smoking is harmful, but it brings nicotine.
Excess weight is harmful, but it brings you happiness.
Being responsible is hard, but life without risk is not challenging. That's why people like to gamble to earn money, they like challenge and want to beat the house. If people said it's risky, they will counter if life itself is already risky, you get a job, you might suffer work accident etc.
