Treat people how to treat you. Teach them how to talk to you. Demonstrate to them how to engage with you. Layout your list of non-negotiables. Articulate your value system. Draw the line at X . Disconnect from Y. Disassociate from Z.
Don't apologize for wanting to surround yourself with people like you. You get one life. Don't spend your time apologizing for other people's behavior toward you. Give them a chance, but give them ONE CHANCE. When people show you who they are believe them the first time.
Change your tune, change your life. And this may mean taking up a new broom to sweep away old garbage. Change your tune, change your life!
There is better waiting for you on the other side of the victim side to you. Don't waist another minute in woe is me. Turn the channel in your life. Embrace the victor in you. You wear it well.
