You have to sell yourself even if you are doing it over the phone. Some people have a hard time trying to do it over the phone...and some don't.I guess in my mind you sell product over the phone and you sell yourself when f2f.
But I enjoy the interaction that takes place, so I guess I'm a bit bias. I will say that I have been speaking to many remote folks these days who say they want to get back into an office setting (non-sales positions).
I enjoy my home office, but I like to work outside my home. Not quite sure how to describe that well... but all the same it is what it is.
