Do you want a good test of how effective your grounding and centering practices are? Try phoning your local motor vehicle bureau. Between the absurd upbeat psuedo jazz soundtrack and the recording telling you that customer service representatives are eager to assist you, you will find your talents truly stretched. Whatever you do, do not watch a clock as the minutes go by, interrupted by further messages that much information is available 24 hours a day on the DMV website. Because if the information that you were looking for was available on the website, you would not be spending your time sitting on the phone.
How well do you think you would do on this test? Do you want to reach out and blast something, yet?
