"The thing that most people do not understand, is that you get to control the way you feel, because you get to choose the thoughts you think. Most people think that they only have the option of responding to the circumstances that surround them. And that's what makes them attempt the impossible, which is to control the circumstances around them, which only feeds their feeling of frustration and vulnerability, because it doesn't take very much life experience to discover you can't control all of those circumstances."
