No, he got rich by taking his 7 dollars in savings to buy 600 postcards to send to people selling his magazine subscriptions for 75 cents for 6 bimonthy issues. Then he bought a typewriter with the subscription money and typed out the first issue at night on his mom's dining room table while he worked during the day as a laborer, drew all of of the pictures by hand, and rented a mimigraph magazine and printed out each issue.
In other words, he had an idea and he followed through. Without him, there would be no Getbig, no RX, no MD.....hell no bodybuilding at all for that matter
