Almost everything is a choice. The difference is that sometimes you're making a rational one and sometimes you only think you're making a rational one and to outsiders and in retrospect it obviously wasn't the best choice, or event a good choice.

There are two aspects to the type of question that was asked. How do you prevent people from ha I g to make choices which are rational and good for their options but still really bad overall, and how do you convinve/educate people about available options they weren't aware of so they don't make outright bad choices when better ones are available that they are unaware of.

There are many possible answers to "why did you take off to the west and ride trains and sleep in parks and steak to feed yourself", but most of them aren't "well I just felt like leaving my entirely stable, loving and supportive friends and family." What to an outsider seems like a poor choice to a specific person imight seem like the decision that saved their life, even in retrospect.
