One day, a friend sent me this text message: "Pay attention to everything you say or do. As it has a great effect on everyone you deal with, no matter how insignificant it may seem." And that made me think of:
What you think of defines who you are. What you say represents your thoughts. What you do explains what you say. What you'll be questioned about is what you do. What people think of you is what they question. And what makes your name is what you're remembered by when people think of you. That, by the way, started by your own thoughts. Then simply, the answer is: You are who you think you are.
Think before you say, and do what you say!
