Answer and Explanation:
Phelps criticized Friedman's position, because he said it was totally irrelevant to analyze the tax functions of inflation without assessing product demand, as Friedman suggested in his theory. He stated that this would only be possible if there was a way to predict an optimal rate of inflation in different situations of demand and supply, otherwise, in Phelps' words it would be the same as "Professor Friedman gave us Hamlet without a prince".
Phelps' positioning would be better considered by the RBC model, since this model is based on real and not imaginary facts.

Answer:
I write a lot about the importance of self reflection--especially come the end of the year. This is the time when, more than ever, it's important to take a step back and look hard at what's been working, what hasn't, and what you can do differently in order to effectively move forward and become successful.
What most people forget though is to audit all pillars of their life. As much time and attention you give your business or your work, you also need to give to your physical body, your emotions, etc. We are humans--we are not robots. And of course it's not always easy to ask yourself, "Have I been happy lately? What do I need to do to improve my emotional well being?" But being aware of all aspects of you is what creates balance--and staying balanced is what allows you to play the long game.
