How I Paid for College on a Paperboy's Salary

I learned that people really can pay for college on their own, just by having a job and saving. I'm not really sure about how he invested his savings in the stock market and benefited from being lucky and making money, because he could have easily lost his entire savings and that doesn't seem wise to me. Now that I've read this article, though, I have hope that I myself can try and save up enough for my college tuition. I liked that he was smart and a success story in this article.
