I send my clients a "disorganizer" in January, so they know I'm still alive.  About 20% of my clients mail their stuff (from as far away as Rhode Island or as close as the next county); 45% drop stuff off (returns are usually mailed back, so they don't have to make two trips in Phoenix traffic); and 35% schedule appointments.  Does that add up to 100%?  I'm not very good at numbers.
