> This is a great story. But...someone who has the intelligence and work ethic to do this probably wasn't going to be homeless for long.

He could have stayed on the street had he not kicked his drug habit. I am amazed that your comment doesn't mention his drug addiction at all - he wasn't just "down on his luck".

That he got over his addiction without support is amazing, but let us not pretend that smart, hard-working individuals can't get addicted to drugs. If you have an addiction, please don't be afraid to get help.
