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 because I believe that 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.
