Some people who have problems with making real life decisions as per making a one pick and sticking with it, should try to use more structured methods with gambling as the focus activity, that is considering they love the idea of gambling already, because I believe that it would help replace every emotional reaction with systematic analysis, which is a core definition of disciplined decision-making.
Gambling activities make one to become hardened and swift and when controlled, it calls for more discipline at making real life decisions.
Although, it is a pure game of chance and could lead to addiction quickly, if one happens to control it by defining it in an environment as a high skill, and with high feedback, with controlled risk management activity, I am certain it could work well and be effective to curb irresponsible decision making in a young adult who is going through life confused.
Don't forget that the focus of using gambling activities here mandates that it must be done in an environment with structure and a feedback team or system to take note.
Your opinion is welcomed!
In order to be able to gamble responsibly you already have to be a responsible decision maker not the other way around, you can't seriously expect someone who is already struggling with the decision making to go into gambling in order to get that part of their lives in track regardless of whether the love the idea of gambling or not, if this method works for you then I'm glad you got through it without becoming the biggest gambling addict there is, that said there is actually no way for me to know for sure so there is that but I wouldn't be advising anyone to take this advice of yours because I am fairly sure it will most likely backfire.
