Happiness is within yourself. You and you alone are the only one who can find it for you. One of the worst mistakes in relationships is to charge another person with your happiness. They will ultimately always fail at the task. If you cannot find a serenity and happiness within yourself, you may have to seek the help of professionals. Depression is not something we often spot in ourself. It can lurk within your emotions and steadily eat away at your life. No amount of money or material objects will counter its effect. I have seen it, I have lived it with others. It is a very damaging and dangerous shadow in our lives.
