Obviously he did NOT do the right thing. There is nothing wrong with admitting a mistake. But it was not an entire loss - he was able to grow with the experience and realize that the lifestyle being sold isn't for everybody. Right, it is NOT for everybody. My advice is that he follows through his new found learning and tries to go back to a job. He is a more mature person now, and will be able to find one eventually.
It's still not obvious to me that quitting the job was the wrong choice. The mistake was what he did afterward in failing to find an alternative source of income. It's a common mistake to quit without an adequate plan, so that is a good lesson learned.
