Go ahead and believe that. Please, continue to agree to your belief that doing what you love will never bring you the wealth you desire.
Please, go on upholding the premise that creating a career from your passion, and fulfilling your physical, mental and spiritual needs, isn't a recipe for financial gain.
Now, stop and think about this rationally.
Is it logical to believe that you can make more money doing something you tolerate, rather than do something you are gifted at? Wouldn't a person have far greater long-term earning potential if they used their talents, and expressed their beliefs about life in their work, rather than say, got some job with a steady paycheck?
