Everything we do in life is a choice. And every choice has either a good outcome, or a bad outcome. Study tonight and get a good grade, or play video games and get a poor grade. Make dinner and have a full belly, or skip dinner and be hungry. Metal detect that park and find that silver, or pass so you can watch a sitcom. Work hard with good morals and succeed, or work just enough to get the next paycheck. Pass on the next drink, get in the car, and drive home safely, or have one more that gives you that buzz and then get pulled over for a DUI (or worse). Pass on trying out a new drug, or take that hit and have problems.
Every homeless person that isn't physically or mentally disabled made a choice at some point in their life that put them where they are now. They didn't think something through, and now they are dealing with it. Want my help? I'll tell you to figure out what choice you made in the past that put you on the streets, and that you should try and correct it for yourself. Don't come to me looking for a handout, a meal, or anything else. You want a job? Sure. I own a business, and I usually have an available position, but make the choice to at least try to look and smell presentable. If you choose to come to me in jeans held up with a rope, and you smell like you've been on a three day binge, I choose not to hire you.
I tell this to my kids all the time. It's up to them to make the right decision, and nobody else's fault if they made the wrong decision. My son (20), is now at Western WA University, and it costs me $0 per year, because in 10th grade he realized that his future was up to him. He went from an average student that went to school and then played video games and what-not, to a student who was determined to get at least one scholarship. He ended up with 4 scholarships and numerous grants, and now gets to go to a private university at no cost. He said he didn't want any school loans to have to deal with, and ended up with more then he needed.
Choices and consequences. It's what life is all about. Just don't ask me to fix your decisions.
