"Want to get to heaven? Avoid sinful desires. Want to live longer? Avoid foods that you like to eat."
At the same time, we are continually given mixed messages about how to live our lives. "Follow your dreams! However, you know most people have to grow up and face the real world. Most people don't like their job; that's life. You can either have the job you want or live where you want, but not both."
It's no wonder psychiatrists and philosophers have been able to stay in business for so long.
