Happiness is something that should be studied. I believe Jim Rohn said, "If you want to be rich, study wealth. If you want to be happy, study happiness." I'm paraphrasing, but I think it's an important idea. Sometimes we may see a doctor that seems happy and automatically assume that, if I become a doctor, I'll be happy too. If you don't really want to be a doctor and you're just doing it because you think it may make you happy, that could be a big problem. We need to make a conscious effort every day to recognize all the things that are good in our lives. We often take too many things for granted. Quick fixes don't last.
