I feel bad for the people whose houses he painted. This guy probably did a shitty job. They're going to need to repaint sooner than they should. Guess we're supposed to be proud of him for swindling/pressuring people into buying a subpar service. Not to mention the employees who are lured into half-baked businesses and lose months of their lives to an incompetent "entrepreneur".
If you love to do a good job, and you find yourself without experience, you will spend more time on it, taking care about the details a professional will know to overlook.
