Changing locations too often. Every time you relocate your practice you will set your business back by at least a year. Even short moves can and will cause some client loss (I lost 40% of mine when I relocated 9-miles away a little over a year ago!) And, while you'll eventually recover from this the cost can hurt or, in some cases, even be financially fatal to some professionals. So, if you absolutely need to relocate choose a place you will stay at. This means really researching your new home before committing it. Then, work like crazy to get your former speed back up!
