I must agree that learning self-control is indeed one of the best advantages that Gambling could give. Though, I must say that before reaching that level of control the path wouldn't be that easy. I myself went through a lot before achieving it, I've almost lost everything I could possibly have and friends that I pushed away and much more. Gambling is really risky and yes it could destroy one's life, though It will still depend on the person who engaged him/herself in this industry on how he would handle it. Self Control would take years before you can say that, I'm in control of gambling.
