5 common mistakes made by self taught DAX students

I am well under way in my career as a PowerPivot Consultant, Trainer and Workbook Hosting Provider. And I have to say (now that I have delivered a number of Rob's "PowerPivot for Excel" training classes) that I am finding delivering training to be one of the most rewarding things I do. It occurred to me recently that people like me (and also Rob, Avi, Scott), that train users in PowerPivot are able to glean useful insights into the way people learn (and incorrectly learn) PowerPivot. Today I am going to share with you 5 common mistakes that I have personally observed - maybe you will identify yourself in some of these things, or maybe you will confirm that you are doing just great. Either way, it is worth a read to either discover a gap or confirm your skill.
