I was blessed to attend several of Zig Ziglar's motivational seminars during the later stages of his illustrious career.  This site will undoubtably showcase many of Zig's uniquely poignant quotes... There was one moment during his teaching when I paused, went hmmmm - that's right... I will paraphrase:

"Some say they separate their business life from their personal life. 
I say that's not possible!
You can't tell me you have a sick kid at home,
and you don't think about that while at work...
or you are having financial trouble at work,
and that doesn't affect your mood/disposition at home."

Yes, it's all part of you... That's why I've chosen to list some personal and business comments together.
