Imagine someone saying to you: "I am your constant companion. I am your greatest helper or your heaviest burden. I will push you onward or drag you down to failure. I am completely at your command. I am easily managed, but you must be firm with me. Those who are great, I have made great. Those who are failures, I have made failures. You may run me for profit or run me for ruin. It makes no difference to me. Take me, train me, be firm with me, and I will place the world at your feet. Be easy with me, casual with me, convenient with me, and I will destroy every dream you have. Who am I? I am your thinking.? What is your thinking saying to you? And more importantly, what kind of guidance do you provide your own thoughts?
