This is similar to the the phrase you are what you think. Do you think you have been mistreated, are you angry, resentful, tired, bored, craving something, or just genuinely unhappy? Your life is a reflection of your thoughts and you need to guard your thoughts as you would protect your family.
You are the master of your mind. Be watchful for any judgment or negativity that is knocking at the door of your thoughts. You have more control than you think, begin exercising it.
