Do you have the ability to do more than one thing at a time?
I'm usually pretty good at it, but I have made some pretty ridiculous mistakes while doing it, especially when it comes to talking on the phone with a client and sending an email at the same time. I'll either spit out the word I was typing or type something that doesn't always make sense.
Those mistakes are rare though, I can usually do 2 or 3 things at once without pause. I actually wrote most of yesterdays blog with a client sitting at my desk. (she thought I was taking copious notes)
