Will you leave gambling if your future wife/husband tells you to do this ?
First, think about what's gambling to me. Is it more important to me than anything else in the world that I can easily sacrifice? Is this habit of me is hard for the people who love me? Is it worth it to quit for them? But if it's negatively affecting my life, then nobody needs to advice me, I will quit at my own will. I don't like addiction to anything.
I don't know about quitting, it depends on the situation, because if gambling helps me get financially stable, then I might rethink about quitting it. Even if it's good for me but my family thinks differently, then I'll consider quitting this for sure. I can find another source for money, but I can't find another source for love easily.
Rightly said it depends on the situation and if gambling is leading to bad financial loss and thinking about your family, it is a good option to quit. Here it becomes very difficult to find source of income, if luck is good it is possible to win once but it will not happen again and again. There is no real alternative to making money in gambling so it is better to find other ways to make money other than gambling where the risk is much lower. You can get rid of negative influences easily.
