This is a disaster waiting to happen. If you already don't have a discipline to stick to one decision, gambling could or would make it worse, because gambling affects you emotionally and psychologically. Thinking that gambling could help replace emotional reaction with systematic analysis is just wishful thinking unless the person already has the discipline to actually keep their emotion in check when gambling. Gambling usually heightens your emotions, so instead of being able to control it, you'd most likely be more emotional and make more rash and reckless decisions.
