To awsner this question I do agree passion is important can passions lead to homelessness?
95% of business's fail in the first year.
Most people's passion's I can assume are music/acting/school teaching/
Most music does not sell for most people to have a enough monthly income.
School teaching requires a bachelor's from a university and years of experience to teach in a classroom.
My answer to most people find a skillset that you can make money from to avoid homelessness, cooking/service skills/security work most of that work pays better.
