I work in a [regular job] because I need the money and have health issues. I also have no desire to have a prestigious job or become rich, because that kind of material gain could interfere with my personal moral beliefs. I've been teaching martial arts nearly 25 years without a break. I've watched TKD people who have a ton of certificates come in and sell black belts in 10 months to casual hobbyists who can't throw a front kick without being off balance even though there's nothing wrong with them. They keep 200 students consistently because people love to be called black belts and brag about their certificates.
What does having a prestigious job, being successful, and being rich have to do with one’s moral beliefs? Is it immoral to be successful and rich? It appears that you are being, dare I say—judgmental. There is nothing wrong with wanting money and prestige, and most people attain it while maintaining their integrity, morals, and religious beliefs; cases in point are Dave Ramsey and Samuel Cathy, the founder of Chic-fil-a.
