Are you a servant?
If you answered yes, you have a master. Do you know that? There are a lot of people who don't. The greatest day of my life is when I changed masters. In this life we're capable of doing that. Sometimes we have to be told or shown that it's possible. To those who don't think that it's possible, maybe you don't know you have a master. Find some quiet time. Do some of that serious soul-searching. It will show it's face after enough time and you will succumb to it's power. That's your master. Do you welcome it? If not, feel free to change it. That's a gift we have as humans, the ability to choose who or what we serve.
