Assessing Macroeconomic Performance

What measuring sticks/metrics you would use in order to accomplish your assessment of how the economy is doing.

Explanation of my question:

Assume you are asked the question, “How is the economy doing?” What specific metrics or measuring sticks do you believe should be noted and/or analyzed in order to arrive at an accurate reading of how the economy is doing and where it is headed. Like, how one should go about assessing the performance of the U.S. economy or the process (focusing on the appropriate variables-metrics-measuring sticks) involved in arriving at such an assessment and not actually assessing the performance of the economy. Can you identify between 6-10 metrics and explain why you chose it and how you would use it. (Not sure if that is too much, just looking for a thorough explanation.) I have an exam in a little while and this would really help me to understand. Thank you.
